MX-3.com

Been having a problem with my Mx-3 the past month or so where its taking like 5-10 minutes to start the car after it sitting over night or period over 6 hours. Im getting spark from the disty so i know its good, not sure about my ignition coil had a few times the plug not hit it right and not start up. my last thing im thinkin is alternator but im not sure how i check all these items. i hate a volt meter if i could get the info to read all these id greatly apprieciate it.

hmm a fuel problem maybe? could be your fuel pump thats my guess.

replaced the fuel pump a month or so ago and i smell fuel when tryin to start it.

I'm really surprised that you battery lasts that long.

I work a dealership, so I deal with lots of dead cars. We have traditionally cranked non stop, or untill you can hear battery weakening. None of this "Crank, stop. Crank, stop" business.

Well, you know what a motor is. Spark, Air, and Fuel. You've got spark apparently. Throwing any codes? Could be a multitude of sensors, maybe your injectors are a bit clogged, maybe a fuel filter is clogged...

Easy way to check fuel pump is get a clean container, take the fuel line off of the rail, and put it into the container, and crank. It should come out at a good pace, so only crank for a seccond, at most.

Its doubtful you aren't getting any air, but if any of the sensors in the intake system are unplugged, it doesn't like it, and may not start.

Doubtful its your alt, I'm not sure how it could cause no-starting. Its only in use when the motor is running...If it runs okay once it starts, the alt is fine.

Disty is notorious. Ignition system sucks in general. I would suspect that... Any cracks in it? Maybe pop it off and clean the contacts. Are your plugs/wires good?

What else could you check.... That exhausts my list for now.

Good luck

finaly found the problem, the fuel pressure regulator was messed up now i need one i was using someone elses to test it out.

well if the sohc regulator is the same as the dohc i think i may have an extra one if it works.
