2002 XX cranks but won't start (Correction, 2001)


TFT

Recommended Posts

Jackie's 2002 2001 XX has been sitting for about 2 months now without running.

I put the battery back in it today to take it out for a ride and it cranks but won't start. Usually when I turn the key on I hear an electric motor (fuel pump?) for a few seconds but now there is no electric motor noise.

Any ideas? Everything seems to be working, and it cranks over very well, it is either gettign no spark or no fuel and I am guessing no fuel.

Yup, that motor you used to hear is the fuel pump. Check fuses where Redbird said, preferably with a test light or meter as they can sometimes crack and not be obviously blown.

All the fuses are right there next to the battery. You should hear that pump come on for a couple seconds when you turn on the key.

Kill switch on? I can't remember if it would even crank in that case, but worth checking. ;)

I had the same thought so I checked and my '01 won't crank with the switch off.

What voltage does the battery read?

If it has enough to crank it has enough for the pump to run.

If the voltage is low--and not necessarily by that much (12.6v or less)--it may crank, but not start. Check battery (12.8v or better) and fuses first.

If no joy, then out of an abundance of caution check the vent lines for raw fuel--an indicator of FPR issues (compromised diaphragm membrane, likely an alcohol laced fuel issue). The point is that you don't want to keep cranking the engine if you're unknowingly pumping raw fuel into the cylinders/crankcase--that can lead to hydro-locking the engine.

If the fuse checks good, vigorously work the engine stop switch several times. Spray it with plastic safe contact cleaner if you have some. Mine actually stalled like that in a Mickey D's drive thru one time. I was troubleshooting as I duck walked it from the order station to the window. I worked the switch several times and it primed and started back up no problem. Never has happened again.

also why is your 02 bird red?

Thanks. The fuse looks good, but I am going to buy some fuses and replace it.

Oops, its a 2001.

It's my wife's Bird. She's the traitor. :)

The fuel pump is not turning on so none of these things apply.

Behind the battery are 4 relays, the far right one is for the pump. It should click when you turn the key on, then click off a couple seconds later. If it's not clicking it could have failed, have a bad connection, or not being signaled--I think the signal comes from the computer.

Has it had any running issues or check engine light coming on before?

The good news is that the relays are interchangeable , so if you need to swap them you can.

Snap your engine cut off switch (Right switchgear) on and off several times. Its not unusual for these connections to show some corrosion, often with inactivity or poor conditions for storage.

If that doesn't work, pull the two bolts from the rear of the tank and snap the dash panal studs out of the rear of the tank. Lift the rear of the tank and support it on a block of wood, a screwdriver, eskimo, something. Remove the electrical lead to the fuel pump. Put your meter across the terminals to measure DC voltage and turn the key on. If you get voltage, the fuel pump is the problem. If not, its electrical and you can work back.

Its probably Obama's fault.

The stop switch also interrupts the starter so it's not the problem.

I have had a battery crank and not start. But you are right...it should have enough juice to fire the pump.

What gives the relay that goes to the fuel pump it's signal? Isn't it the ECU?

In a properly functioning system, that is correct. However, its not unusual to see corrosive damage in these switches, including broken solder joints with intermittent connections that play hob with the system.

Tom, I'll defer to the flight commander. Do not snap the kill switch on and off several times as this is not your problem.

"What gives the relay that goes to the fuel pump it's signal? Isn't it the ECU?"

Yes, when initialized, the ECU sends a signal to actuate the pump for a short period of time to ensure fuel pressure necessary for starting. It does not repeat this unless the ECU power is cycled (key off and on, for instance). Once the engine is running, the signal is sent continuously.

Sorry I haven't responded to my thread earlier. I had to return to Alaska to go back to work.

Thanks for all the responses. Hopefully when I return to Arizona I will be able to resole the problem. Hopefully its something simple.
