Hello. My question is, me and my husband just bought a 2001 sport Trac. The lady we bought it from said it won't start. She said they changed the fuel pump bc they thought that was it. But it still wo
We know its nothing major. We checked the
fuel pressure, that's good, pump is working,
filter is good. We have spark that's good. Oil
looks good. Tranny fluid looks good. It trys
to fire/start but don't. We checked the fuel
safety switch is on, that is. We changed the
crank shaft moduel. We checked the theft,
that's good. All lights work and power on,
on dash, exxx. We tried starter fluid. Still
nothing. Put a code reader on, no codes
found. Put fuel pressure tester on, that's
good. Fuel looks good. What else could this
be? It is not a 4wheel drive.
The basics are there (Spark,Fuel) so the only other thing I can think of, and it is "a shot in the dark" may be the timing or Overhead cam belt (if it has one) jumped position Good luck
i think ignition module
how about a compression test? auto parts store sell gauges cheap
Compretion is good. Tested that.
Timing chain may be busted ...
If it was the timing chain or overhead cam belt, wouldn't that sease the motor up? The motor is not seased. When we spray alternative fuel threw the intake it don't start, but when we took a air hose and forse the alternative fuel down with blowing it down the intake it poofs, and has flames come out the intake. So we know positively there is spark. But bf we did this it has 55psi. And now after we forsed air and alternative fuel down the intake it went from 55psi to 10psi to now this morning 0 psi. Ugggg. But fuel was getting up to the fuel rail, but the spark plugs are bone dry.
No it will not seize an engine ... Overhead cam belt breakage has been known to cause severe engine damage on some cars but if a chain breaks you should be OK To see if the chain is ok .. You need to take a valve cover off.(unless someone here knows a better way) and observe the rocker arms There are much better qualified on here that can tell you how too repair it(my expertise is auto electronics but I can troubleshoot basic engine mechanical problems)
