Re: Gsr swap wont start!!!!!!!!
 

fix the grounds and it should start
mine wouldn't start because my valve cover and tranny ground was not hooked up.

Re: Gsr swap wont start!!!!!!!!
 

might be your wiring on the dizzy. but like it was stated above, check your grounds.

Re: Gsr swap wont start!!!!!!!!
 

Check timing as well, grounds are important but that doesn't sound like your problem. If you have fuel and spark, then you either don't have compression, or the timing is way off

Re: Gsr swap wont start!!!!!!!!
 

What year GSR is it? What ECU? If you're trying to run an OBD2B (99-01 I think) P72, then you'll have to remove the immobilizer from the ECU. It WILL NOT START with the immobilizer in there. Without it, it will throw a P1607 internal ECU malfunction code, but will run fine. H-T user Katman offers a service where he can remove the immobilizer and kill the 1607 code if you don't want to deal with the CEL. Or, you can use a chipped P28 or something.

Also, on OBD2B gsrs into Civics (at least, into 96-00, not sure about others), you have to swap pins A15 and A16 for the fuel pump relay.

I'm not sure if either of these are your problem, since you say you have fuel on the plugs, but they are very common causes of crank/no start on 2B GSR swaps.

YEah check timing and grounding.

Re: Gsr swap wont start!!!!!!!!
 

ground on your harness that hooks up to your t-stat housing

Re: Gsr swap wont start!!!!!!!!
 

do you have the right jumper, as in OBD-2A or 2B?

Re: Gsr swap wont start!!!!!!!!
 

im sure it has somethnig to do with your valve cover ground not being there. i did the same thing when i had just about finished swappin my motor in. i couldnt wait another minute just to put a silly ground wire on. check the grounds.

Re: Gsr swap wont start!!!!!!!!
 

check your grounds, i just ran into the same problem with my friends swap that i was doing.

Re: Gsr swap wont start!!!!!!!!
 

r u running an OBD1 ECU then?

Re: Gsr swap wont start!!!!!!!!
 

first of all thanks for helping greatly appre ok i got my valve cover ground on there t stat one is tigth! tranny to body is good to the gsr is a 94 running obd2 dizzy alter and inject i got a obd 1 harness running a chipped p28 now this is whats funny this motor was on a 92 cx running i drove it my backyard removed the motor i removed my 94cx single cam put in the gsr and now this crap! i played with it today i tried my single cam ecu on it still wont start am surre my timming is good cuz it was running days before i swapped it all i did was swap the engine harness that was all chude up with a new1 from the stealership wired it up and nothing also i check the plugs after cranking numerouse times they are wet with gas so i disconnect the fuel pump and it starts to crank as it was gonna start but goes to regular crank since it ran dry so am most likely dealing with a fuel issue any ideas?????? please need this car running asap

Re: Gsr swap wont start!!!!!!!!
 

You know, if you were going to buy a brand new engine harness you might as well have just bought a '96 - '99 GS-R or ITR harness to avoid cutting and splicing connectors for the alternator, distributor and injectors.

Re: Gsr swap wont start!!!!!!!!
 

well i got this new gsr obd1 harness for 150 new from the dealer i rather get that than 500$ at the stealership so i got is it seem to me like i got a weak spark for some reson! i disconet the fuel pump and try to crank it and it wants to start but it doesent get to start up and plugs stay wet when the fuel pump is connected so thats my only solution i have in mind! while i was doing that last nite starter took a crap and wont turn over now will get a starter after work now!!

Re: Gsr swap wont start!!!!!!!!
 

put your stock harness(the one that came with your car, if you still have it) on it and try it. i had a huge issue with an EX harness i bought and had to completely rewire the dizzy & fuel pump.

Re: Gsr swap wont start!!!!!!!!
 

well what you mean re wire fuel pump and dizzy you got a egine harness or cabin harness? i still have my single cam harness its on the motor i know it will run on that harness cuz i ran the car with that 1 with my chipped p28 mabe i will try that out hey mimik i see ur in miami maybe you can help me hit me up 7862716763

Re: Gsr swap wont start!!!!!!!!
 

got a new dizzy on there but still have original rotor and cap car still wont start!! please help sparkplugs still wet with fuel when trying to start! dont know what else to check any ideas???

Re: Gsr swap wont start!!!!!!!!
 

is your firing order dead on?
check with a screw driver to see if your getting power to your wires from the dizzy, if it dosent spark check your coil, and see if anything came loose or if theres a short that its grounding itself on

Re: Gsr swap wont start!!!!!!!!
 

im having the same problem with my rebuild on my ls, it just turns over and eventually dies down like its my battery thats giving out, i think that my firing order is off, because i just re timed it yesterday, and got that all straight. after school im going to check and see if its my firing order. ill let you know.

Re: Gsr swap wont start!!!!!!!!
 

ok complete dizzy is brand new!! cap rotor dizzy all new still wont start spark plugs stay wet when i take them out after trying to start! firing order is on the money! to me sounds like a weak spark wich i dougth sparks good to me or to much fuel going in cuz it smell like fuel like crazy when i try to start it i dicsconet the fuel pump and try to start it cranks
speeds up like its gona start but then drys out on fuel so am totaly lost now dont have a clue on what it could be please needs some help only car i have! at the moment!

Re: Gsr swap wont start!!!!!!!!
 

i know this is a VERY VERY OLD thread and Im sorry for bringing it back up. But im currently in the same problem. Just did a 99 GSR swap (obd2A) in my 99 Civic EX (obd2B) two weekends ago. I have everything hooked up, and I have a P72-A05 (obd2B) GSR ECU with a crank no start issue. I DONT HEAR THE FUEL PUMP PRIME. So can anyone confirm vindicators comment about swapping A15 and A16 pins on the Civic harness??? Sorry again for bringing up an 8-year old post, couldnt find anything else relating to my issue.

Re: Gsr swap wont start!!!!!!!!
 

OBD-2B Integra ECU's ALL have immobilizers... your civic does not. The car will NOT crank using that ECU unless you can defeat the immobilizer or add the entire steering column from a 2000+ Integra. I suggest you get an OBD-2B -> OBD-2A jumper harness and use a '96-99 GSR ECU.
