Comment from the FixYa moderator staff...

We DISAGREE with the "check the fuel pump" solution.

What you really need to do, is determine if your oil changer is using the CORRECT oil for your car. The correct weight of oil is very, VERY important. You can easily determine if your oil changer is using the wrong viscosity oil....Simply remove the air intake tube from the throttle body, and manually open it. If you see liquid oil present in the intake, you have been wronged by your oil changer. This is a VERY common issue. The wrong viscosity of oil can and will cause you your issue.

We hope that this solution helps you out. Thanks for choosing FixYa for advice

97 geo metro replaced fuel pump, has new timing belt, gets spark to plugs will run with ether sprayed in carb but wont stay running, has new water pump, new fuel pump relay, ...someone said check the ECM...


The cam sensor controls the injector pulse. No cam signal = no fuel. Also these cars are known for wires chaffing through on the injector harness. If any of the wires are shorted out it will kill all the injectors and result in a no fuel no start situation. Check the wiring first, normally a no cam signal will set a code and a check engine light. Make sure the fuses are good also. Hope this helps.

My 92 Nissan hardbody 4x4 etra cab v6, was running a bit rough and when the motor was turned off sometimes you would hear the fuel pump run. I thought my pump was going out.. I went to the parts house, and...


if it is just to injectors run a injector cleaner such a cfome and it should help with that problem if its not the injectors that are the problem and its the computer junk yard are filled with the hard body trucks and get a computer form one of them it should be like $100 if that isnt it then pull the head off and check that and rebuild the head for like $100 that or your oil pump could be a problem.

Hard to start cold but once running is ok


I believe you have a throtle body correct? IF so you have poor fuel pressure, plugged filter of injector.If by some miracle you have a carberated engine the the fuel is leaking from the bowl. Get a carb rebuild kit.

Crank no start: has no spark and only has injector pulse on cyl # 1. if you spray starting fluid directly into throttle body car starts and stays running and has spark and inj. pulse. once you turn the car...


Fuel pump, you have to have press in the rail to fire all injectors- she will run on ether but not good for her. Ck your pump and any related fuses,relays,wiring.

great you got it running... who would have dreamed someone would have filled the car with the wrong gas. E85 has alcohol in it. it will dry out and decay certain plastic and rubber type parts in the fuel system if the car was not made for this type fuel.
