Battling Electrical Problems

[ty.forestcom]

Good Evening everyone.

1988 Ranger 2.9 2wd, manual transmission.

I have been constantly tackling electrical problems. Just when I think I’ve got em, they strike again. Today I stalled out in a parking lot, had a faint burning smell.. I noticed the past couple days it was trying to stall when going from a stop, thought I was doing something wrong. After it stalled out, no fuel pump prime. Cranks strong, wants to turn over. I tried jumping it and it primed, no start. Got it to prime by jumping, eec relay. Jumped the 2 and sent a direct ground to battery. Put an inline fuse from eec power to battery. Probably not a good idea. However, She cranked. Let her warm for a few minutes and tried to drive home, around the corner. She sputtered again few times, caught with clutch. As soon as I ad a decent load, she dies.

Does this sound like eec power? Relays are all good, tried a confirmed working one to no avail. I just installed a 5 channel amp and each channel has its own speaker/sub. Could it be pulling too much power? I’ll be able to work on it more tomorrow. Hoping you have some guidance.

Thanks.

Sounds more like fuel pump. Let's start with some tests.

1. What is battery voltage with engine off? What is it Immediately after startup? What is it after running for about 5 minutes?

2. You need to check fuel pressure with a gauge. It should hold around 35psi at any engine rpm.

3. When did you last replace your fuel filter?

I’ll also add, check your inertia switch because sometimes that connection goes bad.

While you’re in the passenger footwell, pull the EEC, pop the cover off and check for blown capacitors

Was my first thought, jumped it with a paper clip and had no success.
