1991 Capri (the mazda engine) had a severe design flaw in the crankshaft, allowing the timing gear to wobble out of place, messing up the timing of the engine. A repair to the shaft sometimes works (with jb weld or ?), but new crank may be needed...sorry...blueamber

Location of fuel pump relay

A fuel pump relay will not effect spark, and you can usually listen to the fuel pump to hear it kick in 1 sec before you crank the vehicle over. Are you sure you are not getting spark? How did you test for spark?

Why wont start

Ok well there is only two things that make a combustion engine run! If you are getting gas to the fuel rail and it has adequate fuel pressure at the rail then you have a spark problem! Pick up a spark tester( looks like a plug wire in a way but has a light ) Plug it into the first plug on the right side of the motor,(# 1 cylinder) and have a friend turn over the motor. There should be positive spark and the light indicator should light as a constant . If it is intermittent in any way than spark is why u will not start. Then on these years I always start with a new coil or coil packs depending on your type of engine! Hope this helps!! Just my opinion and I could be wrong ! Good luck.

I wrote while ago thanks for the help now my 1991 mercury capri is rattling I have been told it is the cover plate for cat. coverter how do i tighten it? Also clutch feels weak how to tighten?

Sometimes a stainless hose clamp cam stop the rattles, sometimes it takes a spot or 2 of welding.

If your Capri is not an XR2, then you have hydraulic clutch, no adjustment is possible. If it doesn't work right, the master or slave clutch cylinder may be going bad, time to replace them. good luck...Chris

I need to know how to purge the fuel system? This car has been sitting a long time,and i have had to replace the fuel pump,fuel filter,pcm,etc. It will hit occasionally,and is getting fuel,but won't...

This fuel injected motor shouldn't need the fuel system purged.
So the engine hits occasionally?
Did this car EVER run for YOU?
A common problem with 1991 Capris is the timing belt gear will slip around due to damage to the keyway in the end of the crank shaft. Timing gets off, and the motor won't start. A quick way to check this would be to rotate the distributer (after marking its current position) and see if the car will try to start better. If so, then there is damage to the crankshaft that is almost impossible to repair, short of a new crank shaft. Some folks claim to have repaired it, I don't know about that.

Engine starts very hard. Misses and sputters badly when I try to acclerate. I can get it to go by pushing very lightly on the accelerator. Seems to work slightly better when warm. Any ideas? TIA

hi when was the last tim the vehicle had a service? could just be that it needs new spark plugs,fuel filter could be slightly blocked i would start with a general service first

according to a manual , the crank key will point to arrow , the intake cam should have an letter i aligned with arrow on belt cover and exhaust cam should have letter e aligned with arrow on belt cover , and as always rotate the engine 2 full turns to inspect timing marks before cranking or trying to start the engine . if you haven't taken the original belt off yet , paint your marks for quicker reference .
