hey i have a 99 si and it was running just fine and now it will not start, the check engine code is only for #10 which is due to the aftermarket intake. I can not hear the injectors prime, it has a brand new fuel pump. can anyone help? thanks!

 

check the main relay, you should hear it click when you turn the ignition.

 

check for voltage at the fuel pump.

 

coil and/or ignitor

 

where is the relay located I have never had to mess with on before.

 

passenger side,by the glove box.

 

give us a lil more info dude

first check for spark...thats the easiest thing to check....

if you have spark

then check for fuel at the rail...you say you hear the pump prime so most likely you have fuel pressure...

then while the plugs are out do a comp test to make sure you've got compression....with those it should start,,,,,im betting on the coil. . .

Ichecked and it has spark.
I CAN NOT hear the injectors prime
the car has good compression. ran perfect when i pulled it in the garage to vaccum it and i went to pull it out and now it does not work!
I need a little more details about how to find the main relay you said under the glove box? please give more detail. and what does it look like? sorry like i said i have never had to deal with one before. tomorrow i will try the coil then the relay.

 

its a brown box, if you look directly up @ the bottom of the glovebox, you should be able to see it, or if you open the glove box, and look to the right, it should be there. i belive it says "relay-main" on it.


on another note... have you checked all your fuses ?

 

could also be bad connection on your injector wiring... im sure youre not running stock ones... id check that too

the injectors are stock the motor is stock.
I have checked all the fuses that would make since nothing is blown. I am going to check the main relay right now and try putting on a different dist. that i know is good.

 

the main relay is working bc i can hear it click when i turn the key, and i put a distrub that i know is good on it and still not working. I still can not hear the injectors prime. what would cause this?
