truck dosent start

[steechfinger]

i just put it back together and shes dosent want to start its turning but dosent start and i dont smell any gas but i know theres a half a tank. dose it take a minute for the gas to reach the injectors it sat for like a month but i dident take the fuel system apart any ideas? its a 90 5.8ltr with fuel injection

 

[Seabronc]

I believe the 90 has two fuel pumps, one in the tank and one on the frame rail near the driver seat. Check them to see if they are running.

Good luck,

[steechfinger]

the book says that 90-96 have only one pump in the tank and the 87-89 have 2 but dose anyone know about this inertia switch and where its located

 

[Seabronc]

It is on the passenger side under the dash.

my brothers 90 had 2 pumps...can you hear your fuel pump working at all?..fuel pump relays like to go a lot on broncos/pick ups and that could cause it not to start. as to the gas getting to the injectors it should pressurize the system pretty quickly. a new fuel pump relay runs around 15-20 bucks a piece (theres 2)

'90 only has 1 fuel pump. In the tank.

The inertia switch is on the firewall under the dash right above the dimmer switch.

Make sure the two ground wires attached to the rad support are hooked up, they would cause this problem as well. They are held in place by 10mm bolts, one on each side of the rad

If you have no CEL; we do the pinieland method here; on a COLD engine, get some rags and alum foil and cover the engine area around the fuel rail's Schrader Valve, wear safety glasses, and have fire ext ready, but on a cold engine, no one smoking and just a short cranking time, it will be fine.... crank engine; depress valve to see if you can squirt some gas out under pressure.

here is valve's pic Ian's pic of valve

if no flow,

other possibilites as mentioned by other BroncoZone members here;

Clogged filter

Fuel Filter Replacement, EFI type, 87-96 by Ian

Fuel Filter, Clogged/Restricted Fuel Filter & Driveability Symptoms; poor performance, lack of power & hard starting caused for 90-93 by smpcorp.com

Could be the regulator also, a common problem...

not a "most likely cause" tho w/this TSB:

i do hear the pump but my battery is dead and im charging it so when its charged ill go try it again

 

[steechfinger]

i have fuel in the line and it just cranking it wolnt start and im just gonna drop an m80in the gas tank and kiss it goodbye

 

[steechfinger]

ok so i went and took out a plug after i had allready taken off the uppur manafold and they both smell like gas so i guess its getting gas and no spark im and the only thing in my ignition that isnt new is my distributer

 

[firelt90bronco]

On my 90 the inetia switch is on the drivers side, its the thing with the red button, just pry it up.

yo,

This time, do you have a CEL?

 

[Yardape]

Do you have access to another distributer to try? Maybe the pick-up inside the distributor is toast. (too early cant remember the technical name)

Miesk, You seem to have all the technical terms down, What is a CEL? Never heard of it.

Sorry Y, CEL is Check Engine Light; if he has one lit, then he can do a Test for codes; Ryan has best Test article

He can do the Key On Engine Off test; typical Codes for his condition could be;

226 IDM signal not received

654 MLP sensor not in park position

524 When the PCM commanded the fuel pump on, voltage was not detected on FPM.

554 Fuel Pressure Regulator Control (FPRC) solenoid circuit failure

556 Fuel Pump circuit failure

557 Fuel pump relay coil resistance failure

542 Fuel pump circuit failure

[Yardape]

Why cant you pull the gear off? Its just held on by a small roll pin

yes, as Yard advised or get a loaner tool from most parts places, esp the place where you are buying the parts....
