car will not start. help me out please!!

[mikh338]

ok guys so my car will not start. it has a brand new battery, brand new starter alternator is good (even though that doesnt matter if the battery is charged) and everything is hooked up right all fuses are good. when i try to start the car it clicks one time and then nothing at all. i even replaced the starter relay had the brand new starter checked just to make sure its good and not faulty. I thought it mite be an ecu issue so i put a diff working ecu in and it still just clicks one time then nothing at all. I am going crazy I cannot figure it out guys please help!!!!!!

I'm more thinking of things besides your actual injectors as the problem. Swap the CAS, injector resistor pack, and the ECU, and see if it fires. I know you said all the fuses are good. I'm wondering if you popped the MPI fuse when you had the starter wired backwards. Check all of the fusible links in the power block on the battery. Finding the problem in these cases is just the process of elimination.

all the fuses are good on the battery terminal including the mpi fuse. how much can I get a cas for as well as a injector resistor pack?

Both the CAS and the resistor pack are easy things to test.

The resistor is simple, measure the resistance of each on in the pack. There are four and each should read about 6 ohms.

CAS is a little more difficult because you need to get access to the signals. The tests are checking to make sure both signal pins get puled up to 5v and then while you are rotating the blade check that the TDC signals pulses twice per revolution and the Crank Angle signal pulses four times. Easiest place to reach them is at the ECU but it's hard to turn the CAS by hand while looking at the meter.

i tried testing the injector resistor pack and i dont think i was doing it correctly. can someone tell me exactly what part of it i need to test and what pins on the harness and or box. thanks
