How would it be getting too much fuel but not run rich?

Don't think too hard.. the problem is probably right under your nose

possibly could be your tps voltage do you have a check engine light

your extra fuel returns, so no

i doubt TPS, but check it anyways

yes, look for brittle lines, cracked lines...you wont always hear a line, you need to physically run your fingers over every inch. the trees too, at the firewall , and under the intake

I had the same problem on my 50 turned out being a bad ground wire. Check the wire on the back of your engine block and the one going to the block from your battery. Seemed funny to me easiest fix that i tryed last.

No check engines lights at all.

I dunno what the fuel pressure is while I'm driving. I don't have a fuel pressure regulator!! Um how would I check the tps voltage and what is it supposed to be at??? I'm actually thinking it might be the ground on the engine block. Becuz sometimes after I shut the car off even just for a minute it won't/doesn't start back up! And sometime I'll have to get it jumped just so it'll start!! Where is the ground wire from the chassi to the engine??

does your speedometer work? the VSS in the trans that the speedo cable plugs into, if not hooked up will cause it to stale when rolling up to a stop.

No its not hooked up to the speedo! But it is connected to the trans. I can't get it to plug in to the back of the dash. It's like it's to short or something

The ground wire is on the back of the motor. Mine had all these same symptoms and it was the main ground wire from the battery. It would crank slow then hella fast with a jumpstart. After i changed ground cable it worked like a champ all the time.

Well the ground wire is brand new almost on the battery. I have a battery relocation box in the trunk. So either it's not grounded good or it's the 1 on the engine block

not hooked up lol they are all short on everyones foxbody sounds to me like u just looking for easy fix and everything is half ass on ur car just my two cents start connecting everything 100% u might not have so many problems

No everything is hooked up just fine on the car!! I don't do nor do I like nigger rigged shit. This car is my 2nd wife so I take real good car of it!! I'm not looking for a easy fix I would like to fix it for good so I don't keep having this problem. But yes the speedo cable is not hooked up, u r right on that 1. I will hook it up today and check all of the ground wires.

Posted by Blind (Member # 3052) on :
 
for a trunk mounted battery the best ground to use is to run a 0/1 awg cable out of the trunk floor and attach it to one of the quadshock mounting bracket bolts on the rear frame rail, make sure to use a wire brush or grinder to scuff up the area where the cable will be touching to get good contact as well.

and when running a trunk mount battery, you'll also want to add a 4awg ground wire from the engine to one of the front swaybar bracket mounting bolts because the dinky little 16awg ground wire on the wiring harness is not enough once the battery ground wire has been removed.

I do have a 4awg wire grounding under the hood. I did however notice that it's grounded from the ps pump to the shock Pertch but it doesn't look like it was sanded or wire brushed so I'll try to get bare metal to show and hook it back up
