MAN! I DONT KNOW WHAT TO DO!!!! I CHECKED THE BATTERY! THE ECU RELAY!!!! EVERYTHING!!!!! Everytime I turn on my 91' 3000GT SL it just turns off right away! We think its the fuel pump too! But have no way of finding out! Could it also be the spark plugs?! I'm going crazy! Any suggestions?!

 

does it make any noise before it shuts off?

 

Like you hear sounds as if electricity was trying to get throught the wires.....and the motor jumps.....[&:]

 

get a tuneup its probly overdue... new rotor, wires n plugs... it cant hurt. the rotor may be shot thats sending the electricity to the spark plugs..

 

theres a way to find out if its a fuel pump...here step by step...

1.) take off ur intake/ airbox tubing off so u can see directly into ur fuel injection throttle
2.) buy some starting fluid (should come in a spray can)
3.) have someone turn on the engine and give it gas while u spray the starter fluid directly into the fuel injection throttle
4.) it should turn on while u are spraying and if as soon as u stop spraying the engine dies then its ur fuel pump
