swap wont start no spark checked everything!!!

[ej16286]

ok soo i put the new motor in the car it cranks over ... and i got no spark so i changed the coil... still no spark... soo i checked every ground with a volt meter.. all were good...checked power in the distributor that was good also ... soo i then pulse test the injectors to make sure im getting fuel , and i am ... then i figure ok not the main relay soo i go to the ICM ... soo i change the whole distributor with my friends which i know works ... still nothing .... only thing thats different in the car since the swap is the distributor and ecu b/c its a dif motor ... can it be the ecu ??? i tested to see if i got signal and i didnt really get anything ... someone please help me with this ive tried everything lol

you have the right firing order?

[ej16286]

im pretty sure i never disassembled the swap from when i got it i would have figured that to be right ... but i will try that ... im not even getting a spark at all

[ej16286]

i checked firing order was fine... when i test wire 1 with a spark plug to ground no spark at all either ... im lost ive tried almost everything i can think of .. and im sure as always its something dumb or its def the ECU

Im guessing that it could be the ICM or anything associated with it. The most likely cause being the crankshaft position sensor. This has happened to a couple of my friends jeeps and my gsr once. Same exact problem as you. Hope this helps

if the firing order was off you would still get spark just at the wrong cylinder, pull the distributor cap off and test volts at the + side of the coil blk/yel wire. you should read close to 11-12v. if not replace 15a fuse under dash not sure which one it is check your fuse panel

i'd say your ecu or something wrong with your harness if you tried a working dizzy n ecerything.

your ground make shure u got the one on the vavle cove tight and the one on your tranny

your ground make shure u got the one on the vavle cove tight and the one on your tranny

and the 1 on the thermostat housing

try the ecu and see what happenes if not could be ur crank sensor

[ej16286]

yea i was thinking crank sensor ... b/c the obd2 jdm motor doesnt have one ... and the usdm p72 requires one.. i tried the CKF trick too that didnt help soo i ordered a jdm p72 that doesnt look for one ... ill see what happens when i get it ... as far as fuses everything is good .. i have 12.48 volts at the distributor i tested all my grounds to the battery they are all good and tight even cleaned them all off..soo ordered the ecu this morning and i should have it by friday i appreciate all the help

wat year is the car just use a p28

[LS/Vtec]

the ckf trick works for me everytime and the car still runs without it, just throws a cell.

[ej16286]

the car is a 98 the motor is a jdm gsr (96) both are obd2a .. i would just use an obd1 but car is due for emissions lol ... which sucks soo i must use all obd2a... the ckf trick is just taking c1 and splicing it to c4 and then cutting c1 after the splice... and then c11-c14 and cutting c11 after the splice ... if im not mistaken ... ive never had to use it before but i tried and still no luck .. it must be my ecu ... i got it from someone saying it was good but it very well could be bad

[mark11017]

the crank fluctuation sensor down by the pulley does not affect spark. i guess try a different ecu and go from there
