Ok guys I've been trying to get my buddies EM1 running for a while now but still no luck. I just rebuilt the engine and had it started right after and shut it off since the radiator and everything wasn't completely hooked up. After sitting it back down the P28 ecu fried a couple resistor. Just got a new one hooked up along with an sst chip setup like the last one. I now have no dash lights coming on, no fuel pump, and no crank at all. Any ideas on what the problem is

 

You check the big clear top fuses in the underhood fuse box?

 

Frying an ECU suggests that some sensor connectors are swapped.

Also check the G101 thermostat housing, G3 transmission, and G1 battery ground wires.

 

Big clear fuses are good.

We were thinking maybe some of the sensors got crossed but none of the plugs could reach anywhere but where they were connected. If you have some pics of the wires we missed them when re checking

 

Well I would start with the no crank first, have you checked for battery voltage at the starter?

 

Didnt check the voltage but the starter was tested and was good but we had it rebuilt anyways whike I rebuilt the engine

 

The map and tps are easily mixed up

 

Do you have a digital multimeter?

 

Yes I will try the map and tips to see if they are switched

 

Yea and tps is on the back

 

Also ect and vtec are commonly mixed up as well. You you have any stored trouble codes? Both don't explain a no crank situation although

 

Tps and map sensor are connected properly and so are the ect and vtec. We made sure to mark the vtec plug

 

Id start by checking for power at the starter and trace it all the way back to the ignition, I do t have access to my ETM's at the moment hopefully RonJ will chime in soon.

 

Bump come on guys need some help
