sTonedaZn Posted December 7, 2009 Share Posted December 7, 2009 Hi I have just recently blown my head gasket on my 23 z, and had a 79 parts car. So far I've swapped out the good eng and tranny into my 72. I am and also have swapped out the eng wiring harness and some internal harnesses. Everything from my 79 is efi. The problem I am having is I can't get it to run it cranks, but i don't think injectors are firing. I've used a clear tube to see if fuel was being delivered and it looks like it stops at the fuel rails but theres alot of pressure build up. Also I have heard to twice what might sound like it wants to fire. Read the EFI bible and I am having a hard time locating the efi relay .. Do i need this or is there a way I can work around anything if anything just to get my baby Z on the road again. So far 1 week and frustrated as hell:evil: .. Thanks in advance Quote Link to comment Share on other sites More sharing options...
stravi757 Posted December 7, 2009 Share Posted December 7, 2009 Can you give more details, have you tried spraying in starter fluid to see if it will start. Are you getting spark/is your timing right? Quote Link to comment Share on other sites More sharing options...
sTonedaZn Posted December 8, 2009 Author Share Posted December 8, 2009 ya, i get spark from coil --->dizzy-->wires.. But i think it has something to do with the efi not spraying i don't hear it.. pumps works pushes gas up to the 2 the fuel rail then it looks like gas stops moving forward but pressure is still building up.. I also think that maybe has something to do with the efi relayspend today trying to figure out were and if it does need a efi relay or is there a back yard process just to get it running so i can get it to my house..
