i just swapped a 99 gsr into a 99 ex civic. used the stock harness and a 99 gsr ecu. it cranked, and turned on for only a second! what could be wrong?

 

if i put some gas on it as it starts, itl rev up until i let go of the pedal

 

check the fuel pump ................

 

anything else i can try while im at it?

 

Sounds like Fuel Pump... Or, it could be the same problem discuss in this topic.

Try that.

 

i had a similar problem before with a map sensor
Probably isn't the problem in your case, but wouldnt hurt to check.

 

sounds like you crossed your tps with your map sensor. they are both located on the intake manifold and they both have the same connectors. try that out first. keep us posted.

 

we put little things on them to let us know what plugs they were. the map sensor was one of the few we named.

 

when i do the swap using a usdm gsr motor with my stock 99 ex harness do i do nething to the ec pinouts? all we did was extend wires. for no i have to use a 99-00 si ecu till i get a hold of a gsr one.

 

bump

 

you guys think we cuold have gotten some plugs in the wrong places?. would not plugging up the o2 sensor be a prob? friend said his started atleast but threw a code but mine just isnt starting for more than a sec.

 

Why not check the ECU for what codes are being thrown.

 

Check for codes then go from there.

It could be anything from fuel pump to IAC.

 

got it working!

 

what was the problem?
