My car was running great this morning. I replaced the thermostat last weekend and it had a leak so I dug into the engine today and the car won't even stay cranked. It dies as soon as it cranks. It sounds like there is no gas but I know there is. I did not break any vaccum lines but that is what the problem sounds like as this has happened before (broke a couple of lines) but got it fixed Aug of last year. To get to the thermostat I had to take off the UIM, TB, and a couple of vaccum lines and sensors. Everything is hooked up to where it was and when I cranked it to go to town it did not want to stay cranked. If I give it some gas the engine will stay cranked only for another second or two.

 

sounds like my same problem....a lil...dont know what my problem is....

 

is it multiport or what?

 

89 2.8 MPFI

 

same as mine.......a pain in the ****..........

 

For me its really confusing. Before I took the UIM and everyhing else apart the motor ran like a champ besides the high idle. Now it is utter crap. I broke somehting but I don't know what or where. I am clueless. I even too the UIM off again to make sure everything was connected and still together, and from what I can tell everything is hooked up. I'm **** for words right now.

 

You checked everything? Like the MAP, vac lines, distributor vac adv, TB sensors, plugs in the dist, blue spark from the plugs, injector plugs, and when you took the UIM back off - how did the gaskets look?

 

I never touched any of the ignition stuff at all. Everything is hooked up likie it should be. I'll get out there again and check it all.

 

I fixed it. My TB gasket was out of wack. The bottom bolt missed the hole. I opened up the butterfly and low and behold there is the gasket.

 

try the distributor cap and asyl
