So I was driving my truck 2 days ago and all of the sudden I lost engine power. So as of now it will idle a little rough like its missing and will rev in neutral but when you go to drive the truck barely had enough power to go 5mph.
So here it'd whats been done, new cap rotor plugs(copper) wires icm. Ignition timing has been checked 10 times i have 41psi at the fuel rail noid light says all injectors are firing and if I put a 9v battery on each fuel injector I can hear it open and watch the pressure drop i have put a spark tester on each cylender and it is more that hot enough also one bt one and
Watched each plug spark next to the noid light and looked good all the compression is@ 120-130 i have also inspected the entire wire harness and pulled the right valve cover only to find it clean well oiled and functioning..
Wtf!! Oh and if I spray starter fluid in the tb idle is better and the power is back....
89 f250 with a 351 efi (no maf) motor has 10k on a rebuild by previous owner if any one can help it would be awesome!
Should check fuel pressure under a load, static pressure may read 41 (without vac) at idle...but a load changes pump demands as the injector pulse (BTW) is the filter installed correctly...just saying
same problem with my 91, atempted to fix by checking or replacing all of the above, try unbolting your cat at the flange and see how it will run, fixed my problems, installed a new cat and it runs like a champ now, hope it helps
Yeah like stated before, mine did the same thing!! pissed me off for about a week, then i took a gamble bought a new TPS and it has performed excellent ever since...could be your TPS..
