no spark no start

[beballer15]

Hi i am a new member and i have recently swapped out my 3sgte engine with another.( Turns out the number two rod wasnt happy staying on the crank and ended up crackin my block ha clasic) anyway i got the new engine in and got everything hooked up. Now when i go to start there is no spark. I have checked the power going to the coil with a ohm meter and i have power there for a few seconds then it dissappears i am thinking that it is not recieving a crank signal and shutting off the power to the coil so as to not burn it out. If you have any ideas please reply i am getting quite fed up with this problem and just want it fixed

On my '87 Corolla, I had a problem wherein the hall effect sensor in the distributor failed. It could be what you're experiencing.

is that the same 3sgte in those cars? and how did you diagnose that problem

It may be different from the location in the 3sgte.

Here's a good writeup in general on troubleshooting them; the procedure should portable to various makes and models. http://www.wellsmfgcorp.com/pdf/Counterpoint3_1.pdf

i have already some what checked that by hooking up my old distributer too it and then just seeing if there was spark' to a ground but still no spark i think i might go through the whole ignition system and check everything but in the back off my head i feel like it could be just a wiring issue or an ecu issue.

Have you tested coil and ignitor?

I have checked the power going to the coil and ignitor and that acts the same but i was going to check the coil tommorow just found out how to do it and the figures i needed and such. i am not to sure if you have to test the ignitor seperately from the coil or if you just test them together though. Also there is a blue plug that comes out of the haness right before it goes into the the fuse box in the engine compartment and i cant find anything to plug into it not to sure if that has anything to do with my problem though
