Re: antitheft system

TKO is having very similar problems as you and his coolant system is pretty messed up, how's yours?

Re: antitheft system

cooking system is fine,, engine just wont start intermittenly, turns over just no spark, and usually will start after a few hours,, seems to reset if you let it alone,

Re: antitheft system

The eHOW references are very poor and misleading.
ON A FORD:
The PIP sensor in the dist. is an RPM indicator only and sends it's signal to the computer.
Thereafter the computer closes a signal to the fuel pump relay, does the ignition control fire order and fuel control in a correct timing order.
The PIP does not fire the coils or injectors directly.
.
Your intermittant no start is temperture sensitive.
The most likelyhood is the TFI.
Try a can of cool spray intended to cool parts to see if they change operation.

All the signaling goes through the cabling attached between the PIP and the TFI back to the computer.
You can have failure in any one of these locations.
Just talikng and guessing is no way to find the cause.
Some one has to get in and do the work to find the cause.
Is it a lack of fuel, a lack of ignition, or both?
At least this tells you what to go after.
Good luck.
