i have a 90 EF hatch DX with a LSV(b18c head/b18a1 block) sitting in the engine bay in non running shape ..me and a friend just did the DPFI-MPFI switch over per http://www.angelfire.com/d20/hcivic88/dx-siwiring.html and the car will not turn over,the starter doesnt even engage,ive checked my wiring at least 10 times now..the car started up/ran when it had the D15b2 in it so honestly im lost..any help is appreciated

 

seriously nobody has an idea??

 

Have you tested battery voltage? Do you have all your grounds in their proper locations?

 

There are hundreds of things it could be.

Check your battery.
Check your grounds. If in doubt, add a ****-ton of grounds anywhere you can. (Temporarily!)
Check all of your fuses.
Try jumping the starter solenoid by putting 12V directly to the solenoid from the battery.

 

ok update,figured out the cause im the idiot who neglected to fully check the spade plug wire that goes to the starter..the previous owner of my car must of had it on 2 pieces for what ever reason and it seperated under the electrical tape..i fixed it n it cranks over now n does start.

but im having an issue now were earlier today we had it running for about 3 mins after the radiator re-install to make sure it was all good there n it shut off..and it now is throwing codes 4,6,9 and just cranks over but wont fire..ik that cose 6( ECT Sensor (Engine Coolant Temperature) wouldnt effect the firing of it but 4(CKP Sensor (Crankshaft Position Sensor) might as well as number 9(CYP Sensor (Cylinder #1 Position) ..so any ideas on the fix of those? as my cars sooo close to being not a driveway ornimate anymore its killing me.

 

Sounds like the wiring to the distributor is wrong check that first before changing any parts

 

the wiring ive checked a few times compared to a pic of a stock proper mpfi plug after a dpfi-mpfi swap and a guy ik said i shoulda used shielded wiring for the crank sensor wiring,that that is my issue as the surrounding 12v wires are causing electrical disturbance in the .05 volts the sensors in my dizzy use
