I have a 93 SI with a b18c with type are mani. Car doesnt cranck, I hear the starter trying to crack the motor but nothing. Battery is good. Try to jump started and nothing. Any ideas will be appreciated.

 

Could be a few things....main relay, ignitor, coil, timing is off. Any CEL's by chance?

 

dont think is the coil. I swap it out. Last time I check the main realy was good. I'll check it again. Timing is good, car use to run.
Excuse the question but what is a CEL's?

Does your CEL (check engine light) come on and go off after two seconds with the key in the ON position?

 

I think it does. But I'll double check it. If it goes off what then. If the engine light stays on what then?

 

If it comes on and then goes off, does your fuel pump prime (can you hear it turn on then go off with the CEL)?

If the CEL stays on the whole time, then that is a blown fuse (ecu, ignition fuse), bad main relay or bad ECU.

keep us posted..

 

Thats for the FYI poison. I am going to check my kill switch, to make sure its ok. I'll definetly keep you guys/gals posted.

 

Ok, fellows here is the deal, CEL(check engine line) comes on and then goes off after 2 seconds when the key is on the ON position. I can also hear the fuel pump. Any other ideas. Oh and one thing I got the car to start when I jump started grounding to the tranny. If I ground from battery terminal to battery terminal car wont start. After I got the car started. I changered my battery and turn it off and again car wont start. Any ideas. I am in a lost here.

 

do you have all our grounds connected.
1. Tranny to frame rail
2. Valve cover to frame rail
3. Wires to thermostat

 

got the the following ones hook up for sure
1. Tranny to frame rail
2. Valve cover to frame rail

I'll double check the last one Wires to thermostat. What exactly I am looking on this one. Wire color? Ground going to where?

 

it'll have a ring conector connected to a couple wires. should be connected to the thermostat with like a 10mm bolt

 

ofcourse you have a good ground from the negative on your battery to frame rail or something clean and solid right ?!?

 

yeah I think I do. I am going to clean show more metal to get a good ground.

 

if that doesn't work, your problem maybe as simple as a broken ground wire between the battery and frame. you may want to try replacing that before thinking about doing something to serious.

 

thanks for all your help fellows. Found the problem. ground bracket bolts to trainy were loose...the beast fire right up. To prevent this in the future I ran a wire directly from the negative terminal from the battery to the trainy....
