Heres the deal-my car doesnt run anymore. Not good-i was pulling it out of my garage-when it started doing one of its little-stupid, sputter and die things. Now it started back up after a lot of cranking, and appeared to be running rich. Shortly after, it died again, but wouldnt restart-it just cranks and cranks. It still wont run at all, but i think its fouled. Through all of this i got no check engine light, but it was sputtering. Also, somethimes it surged, trying to find an idle. It didnt have this problem until i hooked up the vacujmn to the charcoal canister, and replaced the clogged solid fuel filter. It ran great before, then horrible immediately after. there is no coolant temperature gauge reading, so im going to change both the computer sensor, and the gauge sending unit. i would appreciate any help anyone can give-i suspect the fuel pressure regulator may be bad-where is it located, and does this sound probable. the car sat for several months before i got it, and i had to change several sensors-maf, tps, and iac, to get it to idle smoothly. I changed the electronic part of the maf only, and it cam off of a 96 with a 4.6 in it. Could this cause problems-Once again, no codes, or engine light. thanks.
