rough running after fuel pump replacement

[whitey]

hey guys,

been awhile as i have been getting hammered at work and in the process of planning our wedding.

anyhow my bronco has been running tried and true up until this past friday. got in to go to work, started fine, backed out fine, ran fine until i was halfway down the street then boom! she died and wouldn't start.

being pressed to get into work i towed it to a nearby shop that has done some small things for me in the past. thing was the mechanic i used to see there is gone, so i figured since i had to get to work and it was the same shop it would be ok. they checked for a spark and there was none.

so anyhow, they called me and said they had checked everything, down to the distributor and it was the fuel pump. i told them to go ahead and do the work. i'm under deadline at my job and i have no choice and i need my truck back.

i get my truck back today and she starts fine but, idles terrible and my voltmeter is really low. these things were fine and dandy before it went down.

i took it back in and they played with the distributor and it is a bit better but it is running nowhere near how well it was before the fuel pump (if thats what the problem was) was replaced.

thanks

You need a fuel filter and a new battery. I would take it back and raise 10 kinds of hella with them, but that's just me. Did they switch your good battery for a bad one?

 

[whitey]

fuel filter was replaced. i will raise ****. do you think it is the battery? even my door open chime is barely audible even while the truck is running. and when i hit the gas it bogs down big time.

 

[whitey]

PS please remember my battery and electrical where just perfect before i took it in. the engine would crank full force, all lights, etc but it wouldnt start. now its like it all screwy. it's having issues it NEVER had before i took it in there.

EDIT- sorry JS84 no it's still my same battery. sorry about that i'm just livid right now seems like these guys were just pulling stuff out and replacing it to see if it worked. they really screwed up my truck /emoticons/[email protected] 2x" width="20" height="20" />.

yo *******

do you have a Check Engine Light ON?

if so,

try a DIY Code Check by Ryan

Even if the Check Engine Light is not on - "Don

I hear ya ******...when I was away, my better half let any vehicle sit instead of taking it to a shop; except to get it to a local drag racer that has a shop. He's still humpin' away on his racers and has a very big shop - his sons, bros, nephews all work there and they know their stuff better than anyone outside the mil. knows their stuff.

GL! and congrats!

well i got my bronco back and it is running better. better but, not like it was before. i took it into another place that was recommended to me. the owner of the shop is a good guy and has a bunch of lifted chevy's- well goood except for the chevy's.

anyhow, the bronco has a "serious" misfire. and they cannot find the plug under the hood to plug in the scanner to diagnose it! /emoticons/[email protected] 2x" width="20" height="20" />. we can see the one end that sits near the wheelwell but, isn't there supposed to be another end that plugs into it normally near the firewall that seperates the engine from the interior? anyone have any ideas?

"The self-test plugs are located along the driver

thanks for all the help miesk. this mechanic is actually pretty good but, it is the STI (smaller) plug he cannot locate. he said he'll figure out a way to get a the code out of it. i will give him one thing though, he did locate my coolant leak i've had for over a year- pin hole in timing cover. the saga continues.

the saga continues.

Du, Da, Daaaaaaaaaaaaaaaaaauuuuuuuuuuuuuuuuuuuuummmmmmmmmmmmmmmmmmmmmmmm! Hey ******* Hey Al, isn't there a plug for some kind of diagnostic purpose to the rear of the engine...same general vicinity of the injector harness plug? I found one back there anyway...not sure what that thing is for....but it's three kinds of melted and probably no good anymore.

[whitey]

he cannot get a code and cannot find the STI plug. the previous shop fried my wiring, cut a bunch of stuff. which now explains WHY my door/ ignition chime is barely audible, why my dome light is blinking, why the STI cant be found after they had it. we are taking it into an electrical place tomorrow and basically the are going to rewire it all. bad news- $$ and a shop that completely %&$'d it all up. good news- lots of stuff redone like new. time for a lawyer.

 

[snowman74]

Or at the very least, time for small claims court....

YO JIM!

In 87-96 Broncos the self test plug(s) are behind da air filter box on driver

got the bronco back. the small grey STI plug isn't there. the wire for it is and the metal connector at the end of it but, the actual plastic plug is nowhere to be found. anyone know where i could this plug outside of a junk yard or possibly a ford dealer?

back to performance- the electrical shop spent a whole day on her - FREE of charge. somehow they were able to get the codes. O2 and EGR and coolant sensor they replaced them and it still ran no better. compression check showed 2 bad cylinders, so they removed the sensors and didn't charge me anything. were able to tweak her and get it running much better but i still get intermittent stalls (especially in reverse) but, it starts right up. has power but idles a tad rough. coolant leak is gone now thanks to the timing chain cover replacement etc.

so i obviously have been planning an engine rebuild or swap but, with the wedding, it put it on hold. i guess i'll just have to baby her until after the wedding. but, i'm still not a true believer that all this stuff which seemed to be fine before the fuel pump went down all went nuts at once. never had a check engine light EVER. never had a rough idle or an error code. the truck is a daily driver but only 4 MILES a day or so while i slowly get her like new. in other words she has been babied until i finish her- which went on hold when we decided to get married.

anyone have any ideas? i know the engine rebuild is inevitable (201,000) miles but, anything i may be missing here?

yO ******!!!!

ok, good for now!...some replies after your Qs;

junk yard is cheapest place; or NAPAby wwww, such as Ryan's (shown for cost....he is getting better w/customer service now...)

compression check showed 2 bad cylinders

do you still have the CEL lit?

some info:

"What if thecompression is too low or too high? A. If the compression results are too high or too low, you might consider consulting a professional technician. Modern vehicles are complicated to test and I have witnessed disastrous outcomes when a Do-It-Yourselfer has attempted this test. If however, you are fearless in your endeavor to diagnose the problem, then use the following techniques.

Consecutive low compression in all cylinders could mean that the problem of fuel washed cylinders exists. This means that the engine has had too much fuel introduced into it and all of the oil has been washed off the cylinder walls. The oil creates a sealing effect between the piston and ring assemblies and the cylinder walls of the engine block. Without this thin layer of oil, the engine compression would be allowed to escape into the crankcase. This is common with an engine that has a 'flooding' problem.

If the engine seems to run normally but is weak and puffs a small amount of bluish smoke, it could be an indicator of worn piston rings and cylinder walls. In either of these events, use a small oil can and squirt a little oil into each cylinder, then repeat the compression test. If the compression dramatically increases then you have found the problem(s). If the compression readings do not change, then it would indicate a timing problem between the camshaft(s) and the crankshaft of the engine. The timing chain or belt would need to be checked for proper timing.

If you find the compression reading is very low or zero in one cylinder, it is highly probable that internal engine damage exists such as:

The piston could have a broken connecting rod or a hole in it. A valve could be stuck or leaking. There could be a broken valve spring or a bent push rod. The camshaft has excessive wear and is not opening the valve(s). If the compression is low or zero on two adjacent cylinders, it would indicate: There is a 'blown' or weak sealing surface at the head to block mounting area, which basically means a bad head gasket. The camshaft is broken in an area that operates valves for two adjacent cylinders.

When the compression is found to be too high in one or more cylinders, this would be an indication of excessive carbon buildup in the engine. It can only be corrected by performing a chemical de-carbonizing process on the engine or by removing the cylinder head(s) and physically removing the carbon that is attached to the cylinder portion of the head(s) and the tops of the pistons"

gl on your wedding!!!

hey thanks for all your assistance. i have not seen a CEL yet, have had the truck back for 24 hours. not a whole lot of time on the road yet but, before it showed up within a few minutes of driving it.

thanks for the link to the plug i'll see if i can order one, drive her around for a week or 2 and then take it to another little place i know who runs the diagnostic cheap. see if they can give me a third opinion.

the reason for one last opinion is first shop (idiots) said engine compression was awesome - i believed them because up until fuel pump failure the bronco was a workhorse and never gave me a real problem- and the previous owner had the top half of the engine "rebuilt". second shop shop may have just gotten sick of trying to figure the problem and gave up. would hate to think they did that but, you never know. most of the mechanics out here are SWAMPED due to the heat and lots of cars going down. either way i have 2 different opinions and starting to mistrust all mechanics...
