The fuel system is supplying fuel to the engine and is not causing the 'no start'. The engine is flooded with fuel and will not start until it is dried out.Ģ. If you pull the spark plugs and they are wet then you know:ġ. Clean or replace the components if necessary.īe sure to lube (oil) tube and o-rings before putting the connector back together. Inspect both ends of the fitting for dirt and for burrs. Using a clean shop towel, wipe off the male pipe end.Ħ. Clean or replace the components and assemblies as required.ĥ. Inspect all the connections for dirt and burrs. Use a clean shop towel in order to wipe off the male tube ends. Use a radial motion with the fuel pipe end in order to prevent damage to the O-ring sealing surface. Push the tool inward in order to release the locking tabs.Ĭaution: If necessary, remove rust or burrs from the fuel pipes with an emery cloth. Insert the J 43178 tool into the female connector. Warning: Wear safety glasses when using compressed air, as flying dirt particles may cause eye injury.ģ. Blow any dirt out of the fitting using compressed air. Twist the female connector 1/4 turn in each direction in order to loosen any dirt within the fitting.Ģ. To do this, unplug the fuel pump electrical connector at the pump and crank the engine over to bleed pressure off the line.ġ. If there is any pressure on the line, it will be hard to get apart. To get the connector apart, the first thing you need to do is relieve the fuel pressure from the line. Does it have spark? When you find which system is causing the problem then you can start following that path to find the cause of the problem. With the spark plug hooked up to the coil, ground the plug to the engine and have someone hit the starter as you you watch for spark. Is it wet or dry? If it is wet then you know you are getting fuel.

If all is good with the pressure holding then check for spark. Turning the key on, the pressure should be around 45psi, turn the key off and see how fast the pressure bleeds off. To check the fuel pump pressure, you need to make up a 'T' adapter to tee in a pressure gauge in the fuel line but since the engine does not run just put the gauge in the supply line at the engine and see what the pressure is. Heck, I could throw in throttle position senser, mass air flow senser, camshaft position senser, a wiring or connection problem, etc. Do you have spark? Do you have fuel pressure? Is the ECM sending a signal to the fuel injectors? Without testing these basic systems, you have no path to follow in trouble shooting this problem, everything is just random guesses at this point. You need to check and test that you have all three at the cylinders. I think im smarter nowĪ engine needs three basic things to run compression, fuel, and spark. Im trying to avoid replacing parts blindly.cause I have done it in my younger days. Thankfully I have my sisters car to use for the next 3 weeks, so I dont have to work in a panic but damn.I just spent $38 to fill up !!! Any suggestions ? Once I verify that I have fuel or not I can move down the troublshooting tree. I was going to use some starting fluid to check if its fuel related, but I read that you cannot use starting fluid with fuel injection. so is the fuel pump bad ? Not priming, but running AFTER i crank ? Can someone verify this with their own car ? That wont tell me if its the correct pressure though. I want to check for fuel pressure, but the fuel rail doesnt have a schrader valve for a gage, so im stuck with just disconnecting a line and having someone crank the engine while I hold the line into a bucket. I swapped the EFI relay with the FOG relay and under the dash I swapped a relay with a power window relay. there is one under the hood and one under the instrument panel. Perhaps this system doesnt need to be primed ? Do i have a bad fuel pump or not ? From my research there are 2 relays associated with the fuel pump. So it seems like the pump isnt priming, but when I crank her up the pump is running ? Now im officially confused.

Obviously the car did not start, however when i turned the key back to the position where I should hear the fuel pump priming.I HEARD the pump. Sounds like a dead fuel pump right ?.but this is where I got thrown off.I tried cranking the engine and listening for the fuel pump. I even removed the two bolts and lifted the seat to hear better but I still couldnt hear the fuel pump priming. I understand you SHOULD hear something for about a second or two and that is the fuel pump priming. I turned the key on and listened towards the back of the car and could not hear a whine or hum. I did some basic troubleshooting and found the fuel pump is NOT priming. Ok, now That I have your attention As the topic states, 208K Vibe cranks but doesnt start.
