No engine stated.!

fuses good,? 12vdc on both sides key on?

spark good on all cylinders.??????????

this is first. not fuel, fuel is dead last.

if above is ok the engine runs on test fuel.

if the engine runs for say 3 seconds on test fuel, and SOUNDS

great, that means the spark and engine are ok, leaving>?

FUELING only.

easy , right?

if true all that, then the scan tool is next.

wont buy one,? like most here? (you cant fix cars with no scan tool)



make up or buy a NOID lamp. (a small 12vdc lamp)

see if the injectors are all firing.

if not, the PCM is cutting fuel.

if the injectors fire (electric pulse) then it may be fuel relay not closing.

did you check for 12vdc (11vdc min) at the pump? cranking

you must crank it and check,

there are 3 kinds of cars. (we assume last)

1: pump runs keyon, full time, (illegal now)

2: pump runs for 3 seconds, and stops keyon, (for priming only)

3: runs only cranked, (most cars) and runs running engine.



see that logic there?

some cars cut pump and injection with no spark. ( to cut fires)

this logic is inside the PCM brain, called firmware.

just assume the car is smarter and use #3 above. on all cars

and I win..



the scan tool will show errors cranked for 5 seconds.

does it?



now why i cant leave generic help and answer specifcially

no engine stated.

to fix them you need to know whats there, first.



the line up

1.4 L E-TEC I4 (petrol)

1.6 L E-TEC I4 (petrol)

1.8 L Family II I4 (petrol)

2.0 L Family II I4 (petrol)

2.0 L RA 420 I4 (diesel)





next time post the engine in your car.

open hood , look up see EPA sticker there and engine type?

USA answers... all. of mine, as this is a USA forum../

try to add to one post for one problem not make many unique posts. stay on NO START. please.

SOURCE: no fuel

Hi,
There is break in the wiring to the fuel pump, as you said when you give it direct power it runs. In case you are not able to detect the break in wiring, the only alternative would be to bypass the wiring and put in additional fuse, to make it work with the ignition. You have replaced the pump and that did not fix it , so all in all its a wiring problem.

Thanks
Proton

Engine cranks but doesn't start. Guess there is no fuel for the injectors. Injectors checked, new spark plugs, car has 170K miles.


Is there a fuse for the fuel pump? I'd start there. Then check the wiring for continuity(broken wire).

2003 olds alero crank no start, thought it was passlock. by passed this, it almost starts with either. cycle the key and pump works but no pressure after that.


Make sure you're getting power to the fuel pump after start up. GM cars provide power to the electric fuel pump via the starting circuit when cranking and switch to alternator/battery power via the fuse block and 12v relay with ignition on in run position. Check your fuse block (bad fuse; power not getting to part of fuse block) and fuel pump relay. Could also be plugged fuel filter, bad pump or ?. but not likely because you get fuel while cranking. Check for error codes in the engine control computer (GM OBDII) as well but that probably won't show anything. Good luck and good hunting. I had a similar problem with a Chev Astro. Turned out to be power not getting to one bank of the fuse block because of a burned junction terminal buried behind the battery under the hood. Get out the multimeter and start looking for failed electrical components or broken wires.

It wont start after putting in new fuel pump was that the actual problem to begin with. how about a fuse can you hear the new pump when you turn key to on (not start) if not then check electrical connections fuse, relay, cam sensor, crank sensor. do that in order i listed it as the last part of that is probally not the problem also is there a fuel shut off valve in this car if so try resetting it.

Why won't my car start? It was running last night.


Try start the car again when it is completely dry, if it starts the rain may be short circuiting something on the loom in the engine bay.

If it still wont start,

will it turn over? (car tries to start)
- If it wont turn over the battery would be dead

- If it turns over but wont burst into life then we can go from there ^_^

If the passkey system were not working the engine should not crank and the fuel injectors would be dead. The security light would also stay on.
The fuel pump relay gets battery voltage and also voltage from the key switch. The computer grounds the relay to power the pump.
The crank sensor does not come into play until the engine is cranking and it supplies a signal for the ignition and injector pulse.
Are you not getting power from the key switch to the relay, or from the battery side to the relay ?

Fuel pump won't run unless engine is cranking, but won't start


Are you sure it's running when cranking? It should have come on when key turned on.
This is for camrys up to year '91. It may apply in your '95, also. Check the 7.5 amp ignition fuse and the 15 amp EFI fuse and the EFI main relay, all located in the fuse box next to your battery. There is also the circuit opening relay tied in to fuel pump operation. It is usually found under center of dash. It is usually not the problem, but it is part of the checks for fuel pump operation.
If your car has a " check connector" or "service connector" (also called a fuel pump check connector) under hood on driver's side near the firewall (a little 1 inch cube with a cap on it), then bridge terminals +B and Fp with a jumper wire. Turn key to on (don't start car). The pump should come on. Listen for fuel return noise from the fuel pressure regulator, and verify pressure in hose from the fuel filter. If nothing, check those fuses above. Here is how power runs to pump: Battery to 40 amp main fusible link-to 15 amp EFI fuse-to EFI main relay-to circuit opening relay-to fuel pump-to ground. Ignition switch and the computer (ECU) work the relays to pass power to pump. Hope this helps some, Randy. Good luck.

Help me with my 1993 chevy cavalier 2.2L engine. My car won't turn on when ignition switch is in the on position. When I turn it to the on position, my radio cuts on, and my air conditioner turns on,...


what do you mean by "dash lights"? how do you KNOW the pump isnt working? how do you KNOW its good? at the ignition switch the ORANGE and PINK should have power in the RUN position the BROWN and TAN/WHITE should also be HOT in the run position. There should be a red wire near the fuel pump relay, make sure its HOT when cranking. IF its HOT and the fuel pump doenst run, the pump is bad. You can also put 12V on that red wire and power the pump.

No fuel getting to throttle body / installed new fuel pump and filter / gas is in line but will not come out when turned over


are you geting power to the fuel pump?? On some vehicles the electric fuel pump primes when the ignition is switched on to acc (i.e when all the dash lights come on etc) and on other vehicles the fuel pump doesnt start untill you turn the ignition over to the "start" position. Id check the fuel pump was acutally getting power and go from there

Cranks but wont start


Engine Cranks But Will Not Start

For an engine to run, you need three things to happen inside the engine. Compression, fuel and ignition, without any one of these components the engine will not run.
Basic Checks:

A. Test Fuses. Test both under hood power distribution center and the fuse panel under dash. This is done with a test light tool. The test light should illuminate on both sides of the fuse, if not the fuse has failed and needs to be replaced.
B. Testing Fuel Pressure Test for proper fuel pressure with a test gauge on the fuel rail, most throttle body injection cars (TBI) are between 13 psi and 17 psi. and most (DPI) direct port inject systems are between 40 psi and 55 psi. If no or little fuel pressure is observed and there is 12 volt power present the fuel pump, the fuel pump needs replacing.
C. Checking Timing Belt Test for compression by removing a spark plug and insert a compression gauge. Crank the engine over about 5 seconds the gauge should read between 125 psi and 165 psi, if no compression is observed remove front engine cover to inspect timing belt or chain. Crank engine to observe cam rotation, if the cam does not rotate the timing belt or chain has failed. (note: if the timing belt drives the water pump it is best to replace the water pump at this time)
D. Test for Injector Pulse Remove injector connector to insert injector test light (node) or volt meter. Observe light flash or gauge pulse while cranking. If light/voltmeter doesn't respond, an ignition distributor/crank angle sensor (CKS) or an ignition module is most likely your problem.
E. Test for Ignition Spark Remove spark plug wire, insert an extra spark plug into end of wire, rest spark plug next to a ground source then crank engine. You should observe a blue spark between the spark plug gap and ground source. If no spark is observed, an ignition coil, ignition rotor or spark plug wires might have failed. (always keep hands away from engine when cranking)
