SOURCE: fiero idles but stumbles on acceleration

to me this sounds like your ignition timeing is off because of the hard start and the no power when accelerating. I would definently check the timing out on it
hope this helps you out

SOURCE: 88 fiero starts on it own, but wont stay running.

the brain is not sending the proper fuel pressure codes to the fuel rail to evenly distribute the fuel to the intake and fuel rail.
perform a fuel pressure test check on it ok? also run a diagnostic scan on it and see what codes come out.

You are not getting fuel. EIther bad fuel pump or plugged fuel filter. No fuel pressure and it starts for a second with starting fluid, then there is no fuel being pumped to fuel lines.

Starts then dies & won't restart


check fuel pressure, should be 40 psi.
try 2 things

spray starting fluid in air intake to see if it will stay running. It's fue then.

Try turning key to on nd wait 5 seconds for system to build pressure and pump to shut off. Turn key off, wait for relay clcik noise or 10 seconds. then turn key to ON again and wait 5 seconds to build pressure again. Then start engine. If it starts better, you have a bad check valve in the fuel pump or a bad pressure regulator on the fuel rail (unlikely).

It starts & then immediatly shuts off..... but will keep running if i spray ether into the carb not a plugged injector, not a fuel pump, and the rails are getting fuel


check the fuel pressure in the rails. There may be a low pressure that will not allow the spray to be misted enough. It could be a clogged fuel filter also.

1985 fiero been having problems getting in gear. Now wont turn over starter. New starter didnt fix problem. Dont know if 2 problems are related. Can push start.


Have same car, same problems, easy solutions.

Getting into gear has been improved by putting in neutral with engine running to warm up fluid. The Fiero has very little room in the pedal area. I'm shifting a lot better with smaller shoes.

The problem with starting may well be related to the same issue. There is a neutral safety starting switch. If you're not pressing hard enough on the clutch - starter won't run. According to the Fierostore.com stock clutch pedals tend to bend. They sell a stronger replacement.

My Fiero has been starting just fine the last few days. The last time it didn't I was wearing boots.

I've almost always been able to get it to start using a booster battery, but Walmart's tester indicates that the battery and charging system are fine. It recommends tightening connections. I did this, but still had problems for a while.

My 2001 new Beetle will not stay running. It starts up, then 5-8 seconds later will sputter out and die. If I pump the gas peddle a bit after it starts, it trys to stay running longer but then sputters out...


Hi There,
Try this: You will need 2 people - Have someone Spray Starting Fluid in the throttle then start the car and have someone spray the fluid continuously into the throttle. If the car continues to run you have a fuel problem, but if it stalls out, replace the coil pak. Hope this helps and thank you for using FixYa!

Acts like its out of gas


It is most likely your main relay. You can replace it, or if you are somewhat mechanically incline do a google search on repairing main relay, and you will find info on repairing cracked solder (the reason the problem is intermittent).

poss. is fuel pressure reg. problem. put a guage on the test port and check press. should be above 35psi. see if it stays running when you spray choke cleaner in the pcv valve steadily while starting. if the engine stays running after a few seconds of running on choke cleaner then probably a bad fuel pump relay cause the oil pressure switch will keep the pump on without the relay when it has good oil pressure.
let me know if ya can do this or if it helps.
