1994 302 into a 1993

Recommended Posts

I have rebuilt a 1994 302 and placed it into a 1993 bronco. Not able to start engine. Engine cranks but will not fire.  Have spark and fuel to injectors. I have the 1993 wiring harness in place.  I need some ideas on which direction to head in the troubleshooting process. Is it an air sensor issue?  Is this something that can be jumped out just to make it run?  Any help would be appreciated.

Yo CJ,

Ford 5.0 went to HO in 94  with different firing order and plug wire routing,

From a fading memory, the HO has a MAF sensor, IF SO, you will need the PCM, AKA, EEC IV from the 94 and if you have E4OD, the PCM must be from an E4OD equipped Bronco.

Yo CJ,

Speed Density to Mass Air Conversion & Parts List with Cost in a 93 F150, 5.0, E4OD; "...For this article, I will be doing a 93 Ford F-150, 5.0, E4OD trans. Because they don't make a kit for this, I will be re-wiring the harness, and using a PCM and MAF out of a 95 f-150, 5.0, E4OD. If you have a truck with a non-electronic Trans, like the old AOD's, or C-6's, etc, you can use a MAF conversion kit..." Read More

Speed Density to Mass Air Conversion for Bronco & F 150; "...To convert SD trucks with E4OD/AODE transmissions to MAF, some people use the CA 5.8 MAF/E4OD (F5TF-12A650-BYA). Mike Wesley says he uses the F5TF-12A650-HB (95 CA 5.0 MAF/E4OD) on a 750+ HP daily driver 415 stroker Lightning with a Vortech S trim. It runs open loop, has been reprogrammed, drives like stock, gets 17 MPG and will run low 10’s at 130+ in the 1/4 mile and A/C and cruise work great. Both of these EEC’s are set to use 4.10 gears. If a smaller ratio is used, say 3.55, you could use the F5TF-12A650-GB. There are probably 15-20 EEC’s available to convert a SD (later model) to MAF (some of these may compromise the ability to stay emissions legal). If you have an early SD truck with AOD, re-wire to the Mustang EEC (Ford MotorSport sells this kit). You’ll have to move/add quite a few wires, and you might not like the results if you’re not able to re-calibrate the EEC (like the Pro-M ’low cost’ kit, Kenne Bell, LCA and Downs Ford come pre-re-calibrated). The engine shuts down at 85 MPH, shifting is fairly sloppy and too early (at least on a Lightning). All Ford EECs shift poorly -- except for the Lightning, which is only slightly firmer. To use the Mustang EEC on a truck with an E4OD/AODE, you would need to run two EECs in parallel. The Mustang EEC runs the engine, the existing truck EEC controls the trans. Pro-M sells a kit like this..." READ MUCH MORE
