My original thread. -------> //www.fiero.nl/forum/Forum2/HTML/128235.html

Seems like this problem cleared up somewhat. At least to the point of not cutting off, until yesterday, 4 times. 3 times sitting at lights and once traveling 40mph on the highway. All restarts were hard ones. Still been having running smooth issues and bogging down when taking off. While playing with the throttle in the driveway. Hit the gas hard and it stumbles a bit before catching. All cold starts seems to take a little effort.

Soooo. I did a fuel pressure test, (again). This time it was pegging around 9-10 PSI idling. Juice the throttle and the engine would stumble and the pressure would drop to 7 PSI or so and then go back to 9-10.

I know that the pressure is supposed to be running at 9-13 PSI, but mine is on the low end of that scale. Looks like fuel pump (with hose), filter & strainer replacement tonight. Hope this is the final fix. Any other ideas???

I would do the filter first and wait on the major work....you might get lucky.

Already did the filter way back at the beginning.

I hate replacing in the tank fuel pumps in any vehicle, but hey we are lucky in that our tanks only hold 10/11 gallons of gas when full, how would you like to change one in my 94 Suburban with a full tank, 41 gallons?

have fun.

Yes, they're a pain in the tail. Luckily the ones that I had to change I had the opportunity to burn most of the fuel.

So far, so good. No hesitation in about 20 miles this weekend. We'll see what the next week brings in the next 600 miles.
