okay, the jdm gsr is in but there are some issues with it..... it didn't crank over until the third attempt and it let out a loud popping sound before firing...... the idle is terrible, it sounds like a domestic with huge cams..... beyond that there is a LOT of vibration, especially from the timing belt side..... what could be the problem?

 

update: it starts okay, but with a little gas it is definitely backfiring...!! is my timing off?!

 

most likely. do you have a timing gun? Are your plug wires on correctly?

what kind of car is this in?

 

might be that my #2 and #3 wires are crossed...... the firing order is 1-3-4-2 from lower left going counterclockwise, right (on the dizzy cap, i mean)?

 

it should be 1-3-4-2, does your setup look like this?

3 4
1 2

 

no, the #2 and #4 wires were reversed...... i changed them around, but now the motor just wont start.

That is correct, you do a timing belt too?

 

lets start out fresh, what kind of vehicle, and what engine/ecu are you using.

 

okie dokie.... got it started. turns out the wires were crossed.... corrected them and now it's running. thanks.

 

good job...i did the same thing changing my cap and rotor..it was LOUD as POP..it scared the crap outta me..i though something seriously whenn wrong..but its all good after i corrected the wires...
