Cranks but will not start. not getting fuel, replaced cam and crank sensors. it would not start after being shut down for a few minutes. after sitting for half hour it started and ran fine for about two weeks. then it just would not start again. I replaced the sensors and timing belt after about three weeks of fooling with it it started and ran fine for about two weeks again, then it would not run again. has not run since.

Hello,

This sounds like you have a MFI relay they is not working right. Here is a guide to help you test it and the location of the relay in the fuse panel. I have also included a engine wiring diagram so we can get on the same page when testing.

Check to see if the system has voltage which will confirm the relay failure.

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
