Default 93 no start issues

okay just pulled my shafts and did the u joints now it wont start hardley and if it does its only for a few seconds, when i bought it and drove it home it had a power cut off goin down the road a few times stopped at the store and did a tune up and ran great the rest of the way home, so its got new plugs, wires, cap, and rotor. that leaves me with the coil the cps the tps and the iac. but the issue that happened today is i pull it out starts fine then dies about 30 seconds later, get in to start it up and it just cranks and cranks and cranks, if it does fire it cuts off right away and only starts under throttle. so other than cps tps and iac and coil what might you guys suggest i do about it and how to go about doin that. sorry for the book but thanks for reading, oh 4.0 with the auto tranny too btw

Still pondering possible causes but in the meantime..Have you checked for any stored trouble codes in the computer? You might have some in there even if the check engine light never came on

I was dealing with the same issue of only starting with throttle. Had the IAC recomended (which makes sense), and it started right up.

im guessing that your issue is gonna be the same as mine and end up being the cps that needs replaced or the connections cleaned or the sensor its self cleaned
