94 MX-6 Starting issue

HI,

My MX-6 would not start the other day. First thing is when i leave the car sitting 4 a couple of days without starting it the car would need a jump. Yesterday around 4pm i turned the key, the car started but died..tried again it started then died but it remains running as long as i am giving it gas and when i get to a stop sign it dies unless i put it on neutral and give it gas at the same time.

This morning it was cold, it started and 5 minutes later it shut off, i looked at the rpm, it was below the norm. I noticed the needle dropping then moving up a bit as if i have a vaccum leak.

Any idea?

    Thank YOu Stormbrewin....



    My mechanic placed another battery in the car, then he tested a few things and finally he had to raise the rpm so that it runs a bit above 1 but as i drove it to complete a project, when i get to stop the needle start to drop below the 1 again. I will certainly try your suggestions above and will repost after.



    Thanks

You may have a fuel pump issue or pressure relief problem Try squeezing the fuel return line/hose with the appropriate tool so you dont damage the hose and see if thiers any improvement as it could be bypassing back to the fuel tank.Also are the air box /air filter and associated inlet tubes tight with no leaks or splits.If the inlet system is leaking it upsets the air flow meter and acts like a vacuum leak.you are right as it could also be a vacuum leak

check the fluid levels in the battery and if your battery is pushing 4years old, i would purchase a new one anyway. check the security of the terminal post the may be slightly loose.

You should've changed the coil when you replaced the starter. If you could only do one at a time, I would've gone with the coil first. There is a brass plate that gets charred with carbon build up. Your banging on the coil shakes some of it off, re-establishing a good connection. You can sometimes get away with taking it apart and cleaning all off with a mini-grinder or rotary wire brush. This will confirm it for you and buy you time until payday or your next day off.

Starting and stalling issues in a 94 Z28


you have a egr system problem, most likely an oxy sensor. also check the intake sensors as they will corrode easily when let set without starting for awhile, this is why any mechanic will tell you to start a car daily and let it idle for a few minutes. (if it is a daily driver in your position)

About the only thing within time that can change from sitting that would effect starting performance is the fuel. The fuel is probably evaporating from your lines and other areas of the system.
Try turning the key to start with a pause till you hear the fuel pump stop, THEN turn it to run.

2001 S-10 4.3 Vortec trouble starting after 3 days of sitting


I would start with the fuel filter, then the fuel pressure regulator. If those two are not the source of the problem you may also find the issue in the idle air speed solenoid. A couple of other places you can look is the air filter, the mass air flow sensor, or actually just cleaning the throttle bore. Hope this helps, good luck!

Doesn't always turn over


It sounds like your battery isn't holding a charge. Regarding the starting, you may have to replace your starter solenoid. Although many cars do not start if the brake pedal is not depressed, the thunderbird is not one of them. I have one outside in my driveway right now. There are unfortunately, numerous electrical glitches with 89-94 Thunderbirds. I have replaced many many electrical parts for both of mine (a '90 v-6 and a '94 v-8)

When we turn key car is dead. Car has been sitting for 2 months.


replace your battery, a battery discharges every day you dont run the alt. to charge it up... after a week or 2 weeks the battery would be dead, just from a car sitting not being started... if you are not using the vehicle, it is a good thing to replace the battery, and every couple days just start the car up and let it run a while to charge the battery.... if you are going to have to leave the car for a while without starting it, then disconnect the battery, and remove it from the vehicle... you can buy a cheap trickel charger for the battery when it is out that will keep it charged till you decide to put it back in.... hope this helps you...

1990 Mazda MX6, Turns over, will not start


Do you have any enemies? Did someone contaminate the fuel? Also, was it parked near a field, or somewhere near where there may be mice or other rodents? Check for water in the fuel system, it happens this time of the year.
