Starter Motor help
Discussion
Hi
have previously posted up here about starting trouble
Ok here is my thinking and wonder if anyone could advise or push me in the right direction
Head gasket went on my 1991 1.6 8v xr2i had to have the head skimmed etc so it obviously got really hot,
once i got it back it would turn over a couple of times before firing up, this carried on for a while until it started to turn over more and more but still started now it turns over and over until the battery is almost dead before firing up i know that all the basics are ok
plugs
coil pack
fuel supply
compression
relays etc are all hunky dorey
so my thinking and working along the lines of everthing puts me now at the starter motor i have cleaned up all the contacts and earths and still no difference it still wont start until almost dead
so my thinking is did the heat from the engine when the head went damage the starter motor and over time it has slowly killed itself does anyone know if there is a wire from the starter motor that tells the ecu that it is turning and can now make the spark at the plugs??
when the head went it blew a water pipe which went all over the engine!
again any help or advice would be greatly appreciated

never tried it, but what would that tell me if it does start ok or not ok with a bump/tow??
If it is still difficult to start, then I would rule out the starter as the cause of your troubles.Edit. Are you using the old hydraulic lifters ?

As far as i know the engine is standard
the reason i am drawn to the starter is when the head went the car stalled and when i turned the car over it was very slow when cranking,
also i was advised in order to test the alternator once the car was running to remove the large positive from the wire and see if the car would run ok when i removed this wire the engine quietened down when i reconnected it there was a funny whuring noise from the starter again!

Often when head gaskets rupture the engine seems slow to crank as the cylinders admit water.the reason i am drawn to the starter is when the head went the car stalled and when i turned the car over it was very slow when cranking,

To test the alternator all you require is a multimeter across the battery, should be 13.5 -14.5 volts ish.
If the starter is running continuously it will soon be goosed, usually caused by a sticking ignition switch.
My comment ref. the hydraulic lifters, was not implying that the car was modded, more that the older contaminated units could be an issue as regards valves not opening , until prolonged cranking had built up sufficient oil pressure.
M-Ster said:
yeah someone else mentioned to me that if the incorrect oil filter was fitted it allows the oil to drain back and subsequently the pressure to drop does the car have a safety circuit whereby if the oil pressure is too low it will not tell the ecu to spark??
Nope they fire up and rattle their wotsits off until enough pressure has built up. The oil filter doesn't normally cause this, it's the crud in the sump blocking the strainer on the oil pick up tube.BTW ,These engines don't take kindly to being overfilled with oil.
when it does eventually fire up it runs lovely smooth tick over and revs up nicely oil is clean as hasnt done hardly any mileage since head was done.
If the starter motor is sticking would it not then not crank when turned over after it has been switched off and on again?? or can it stay stuck in yet still crank??
apologies for all the questions but its not often you get someone who knows what they are talking about

Yes starters can occasionally stick and still crank. You really should try bump starting, and if it does fire up readily , get yourself a replacement starter.If the starter motor is sticking would it not then not crank when turned over after it has been switched off and on again?? or can it stay stuck in yet still crank??

Good Luck, and I'm sure a Ford fan will drop in soon to assist in this troublesome matter.
only trouble i ever had with a cvh starter was hated cranking when it was warm as the exhaust was too close and used to over heat my starter, have had trouble before with cold starting that turned out to be the timing at the dizzy, ( advance and retard system) with a bit of a tune up started winter mornings on the second turn every time.
Ok have today managed to rally a few people togeather for a push and the car started every time on a bump start, after a couple of times i tried starting it on the key and usual thing of turns over but wont fire give it a push and it bump starts straight away so do you think we can safely say its the starter motor????
Hi just to let you know fitted starter today turned it over and fired up on the button thanks for everyones help
I now have the fun task of fitting all the new parts that i have accumulated over the months that it hasnt been working
it just goes to show a problem shared is a problem sorted!
