Ahhh. you have one of the first verisions of fuel injection... check all your vacuum lines, had a 89 ford f-150 I-6 with a similar problem years back. did everything from change vieciel speed sensor to the oxygen sensor... it was a tiny leak in vacuum line... Good luck!!

F-150 ford truck check engine light keeps coming on


Did you replace the gas cap? Also check the filler tube that's where the gas cap snaps on where you put gas in. The filler tube or neck has a thin lining of plastic at the top look for small cracks in it where the gas cap goes on. It there's cracks in it, it will cause an emission leak and sometimes a dealer won't find it until you spent a lot of money on diagnostics. And it depends if there best mechanic was working on it.

I have an 89 ford f-150 cranks wont start got fire, timing is right, fuel pump is pumping


Hi,
Since you're sure that you are getting gas and fire and timing is right... (also check firing order), has anything been done recently that could help you locate the problem? Such as removed distributor (could be 180 degrees out)? New plug wires (maybe crossed)?
All else I could recommend is checking cylinder compression (In case the valves are the problem)... The engine timing chain could need replacing...
Hope this helps... Good luck!

Ran out of gas ,now drives rough 1990 150


Hi there it is most likely dirt in the fuel filter,when you run out of gas you bring up all the crud from the bottom of the tank and if your lucky enough that it hasnt ruined your fuel pump it should be just the fuel filter needs the dirt blown out of it a really easy job to do good luck
