95 tbi stalls

[badluck]

It started stalling after restarts but it would start and run. This happened three or four times over three months.Then it got to were you would be driving and slow down, it would stall.This happened four or five times. Let it set five minutes and restart. Then it got to were it wouldn't start.Checked and found that I wasn't getting fuel at the tbi. Then tied starting fluid,this would get the truck to run for three or four minutes and then stall.Changed fuel filter, didn't help. Changed fuel pump, didn't help.Checked fuel pressure with a kit at the fuel filter, getting 15psi. I left the gauge on the system and used starting fluid to see if the relay was dropping out causing the stall,but I would always have pressure and could hear the fuel pump run for a few more seconds. Changed fuel regulator,didn't help. I have a 94 that I swapped out the MAP and idle air control valve. The 94 is still running. Checked EGR to see if it was moving in and out.After doing this I was able to get it to restart but would stall after putting in gear. This went on five or six times. Checked elect connections ,didn't found any that looked bad. After the five or six time the truck started and ran fine. I thought maybe the connections was the problem. Drove the truck around the house for a few days to stay close. No problems. Today took it on a long trip. It left me on the side of the road. Back to stalling when you slow down. wait five minutes and it restarts but stalls again. This afternoon was able to restart after work and drive home thrity mile no problem. Also checked batt. cables. Sorry for such a long thread but was hoping the more info. the better. Please help

man.. is your fuel pressure ok at 15lbs? I dont know where it should be, but i thought it was sposta be more up around 50? when it kills, does it sputter-out, or just stone-cold stop?

TBI uses a lot less pressure than MPFI, so 15 PSI is right on the money.

As for the stalling, it may not necessarily be a fuel problem. Try checking your ignition system. Does it have a real rough idle? It could be a timing problem, battery could be on it's last leg, who knows.

no rough idle, the truck runs good when it wants to. The batt. is only a year old. When it stops it stops.

What about your oxygen sensor? It didn't kill my truck but it ran really rough when it went bad. Don't know for sure if it could be that but wouldn't hurt to check. Mine screws into my exhaust pipe on the passengers side just below the cab.

Thanks , I will have to try that, it wouldn't hurt with the price of gas. I have been driving it around the house again and it running fine. Don't want to take it on a road trip again.

At last,found what was causing my problem. Ignition control module on the distributor.
