So you have used the Noid lights to see if the computer is pulsing the Injectors, and you have GOOD Kv on the spartk minimum 25-30 Kv's?

Also it might get gas but how much gas? you need to perform a volume test there is a certain amount of fuel the car needs her minute to sustain demand load variations.

Is it port injection or thortle body? What engine is ? if its port injection your fuel pressure is to low , if its a throtle boty i think 15-18 is minimum to keep the car running, might have a bypassing fuel pump in the tank.

Need more info.

My 98 ford explorer wont start its turning over and getting spark and fuel


OK IF YOUR YOUR SURE YOU HAVE SPARK AND FUEL THEN THE PROBLEM IS AIR OR COMPRESSION I WOULD THINK COMPRESSION DO A QUICK COMPRESSION TEST AND I THINK YOU WILL FIND THE PROBLEM IS A BROKEN TIMING CHAIN ONE OTHER POSSIBILITY IS A PLUGGED CATALYST BUT FOR BOTH BANKS TO BE PLUGGED TO THE POINT IT WILL NOT START IS VERY RARE GOOD LUCK (WHEN YOU SAY YOU HAVE FUEL DO YOU MEAN THE FUEL PRESSURE IS GOOD AND YOU HAVE INJECTOR PULSE OR JUST THAT YOU HAVE GOOD PRESSURE THE INJECTORS MUST PULSE AND HAVE AROUND 45 TO 60 PSI (RULE OF THUMB) FOR IT TO START ) USE A NOID LIGHT TO TEST INJECTOR PULSE OR IF NOT AVILABE SUBSTIUTE A 194 BULB AND BEND THE WIRE TABS FROM THE BULB DOWN AND PLUG THEM INTO THE INJECTOR HARNESS (NOT RECOMMENDED FOR ASIAN OR EUROPEAN CARS ) THIS LIGHT WILL BLINK WHEN CRANKING OR RUNNING IF YOU HAVE INJECTOR PULSE

I have a 2003 Oldsmobile Alero 3.4L that wont start. I have done fuel pressure test 50-55 psi and plugs have good spark. However when done light test on injectors there is no response so there is no pulse....


Is the security light staying on ?
Usually the engine will not crank and you have no power to the fuel pump if the security system is disabling the car.
No injector pulse but spark would point to the computer since both use input from the crank and cam sensors.

Try the fuel injection relay they are located under the hood. They blow out every few years on my Volvo. The car starts to quit all of the sudden. It is either red or green colored. It is located in the fuse box under the hood.
