cant get car started

[91dsmgsx]

i just re built my 91 gsx had it runnung for like maybe 10min and couldnt get any throttle respone found out that the revious owner wiried in a diff. tps,got that fixed then tryed to re wire the fuel pump and i thing i blew the MPI relay in the prossess and relocated the battery to the trunk i was wondering if i re wired the fuel pump wrong while the battery is in the back if it would still cause the relay to blow i replaced the coil pack and tested the injectors and everything checked out but it still wont start theres no spark or gas would it be the MPI relay or something else if anyone can help me out it would be great

It would help if you would edit your post to add punctuation, etc. It's hard to tell where one problem ends and another begins.....

Also, can you use a multimeter?

[blackrosenova400]

I should come down and help you Im from Belle Plaine. How do you know you have no spark? How do you know you have no fuel?

Talk to me on aim if you got it AIM name blackrosenova400

[91dsmgsx]

no aim and yes i know how to use a multi meter i used a spark tester and took out and injector to see if it sprayed gas during start up and no gas...i did all this work myself so im fairly familiar with dsm's and i went to school for a semester for automotive service so im not just running blind here

Listen for the MPI relay when you first turn the key, it's under the center console by the ECU. You can take it out, take off the cover and you'll see if it's blown or not. There's also an MPI fuse right on the positive battery cable, whatever you did with that when wiring up the rear mount battery. Those are always a PITA.

i know where the relay is i took it out and tested is with a multi meter according to the hanyes manual and the fuse was blown but i replaced it and but the battery back to factory setting and still no start,spark or gas

Pay me and ill come down tonight :). Im sure we could get it goin. I have an A.A.S. degree is diesel mechanics, yet I am still convinced a have far more knowledge spark ignition engines.

Sounds like your computer is getting no power. Try to check for codes and im pretty sure if you get a contant 12v your computer isnt getting power or there is a problem with your ecu.

[SnoEclipse]

check all of the engine/ignition/fuel related fuses and relays.

Also use your meter to check for 12 volts at the injectors, etc.

im broke at the moment blackrosenova400 and its kinda my project car i vowed to not pay someone to fix it but if your not but tomorrow and feel like driving down let me know
checked all fuses and relays and the computer could also be the cause but the connector to the relay is getting the correct amount of voltage to it and i know that if that relay doesnt work neither does the spark or the injectors
