1988 mx6 died

myers_69885 · 11-15-09, 14:27

I was drivin my car and all of a sudden died. I am a diesel mechanic and have suitable knowledge of cars. have checked all the usual things likethe timing belt,fuel pump and if the car is getting spark.Have been working at it all day and it did try to start a couple of times and did start once but than bogged down and died again, and now wont even try to start. the car ran excellent before this it only has 120k on it.and hand plenty of power and was really fun to drive. If you guys can give me any suggestions it would be appreciate it.thank you.

Is turbo or N/A? Have you check Thorttle body Boot for any cracks?

fuel pump or fuel filter

**randys626turbo** · 11-15-09, 18:32

or maybe check the maf and see if the connector is plugged in all the way just go over it i bet its something easy

I have checked the plug for maf and cleaned it just to be shur.fuel filter has been replaced just i case and get the same results.just tried to start again but bogged down again. I am getting fuel when the car is crankin, but dont know if correct pressure will check pressure tomorrow.Is there two filters on the mx6 n/a

did replace fuel pump last year but was an O'reilys special.

Have you checked the coil? I had to replace mine when the car had about 120,000 miles on it.

**randys626turbo** · 11-15-09, 21:56

distributer could be going bad too i had to replace mine at 150,000 on my n/a

myers_69885 · 11-15-09, 22:06

replaced distributer about years ago. but looks like I am getting good spark. I havent check coil yet but seems fine.

i'm leaning towards possible bad pump or FPR. I've seen some bad fuel filters but i yet to see one cause a car not to run. I'd check that fuel pressure and see if its around 40psi.

myers_69885 · 11-21-09, 14:55

just checked the fuel pump and the pressure is 50lbs. cant find anywhere where it says what it should be.I have a Chilton manual and it does state 64-85lbs for a 1988 RX-7 witch uses the same pump.I am figuring that it is bad, but i could be wrong.some one stated that it should be above 40lbs

Were you having any problems before it died over heating, misfiring anything?

myers_69885 · 11-21-09, 22:49

No i was haveing any problems with overheating at all. No misfiring either.
