Got a 87 F150 w/ 200,000 miles. Lately after driving for a few minutes and turning it off it will not start up. If you wait 20 or 30 minutes it will finally start. It is getting fuel and it is getting fire. We have spent 3 weeks working on this and here is what we have changed. Distributor / pickup coil, MAP sensor, coil, plugs, TPS sensor, Temp sensor, Cap, Rotor. Checked Fuel pressure, and codes. The thing is not throwing any codes at all. Runs great once it gets started. We need help bad !!!! Any suggestions???

 

when it does start is it running properly right away or smoking ?

I was wondering of you have a leaking injector causing flooding.

 

how do the plugs look?
