So I have a 99 Honda Civic EX. The other day I noticed i was running a bit leaner fuel wise and was lacking some power during acceleration. A few days later the car lost the ability to accelerate while climbing an on ramp to the interstate. It eventually sputtered out and died. I diagnosed the fuel pump as being bad (it was failing to kick on and prime) and replaced it with an OEM part. I also decided to replace the fuel filter at this time. After replacing the fuel pump, the car started and ran for about 4 seconds. It then sputtered and died, failing to start from that point on. It will crank but is simply not starting. The new fuel pump is priming, i checked to make sure there is fuel running to the filter and from the filter to the injectors.
This is where it gets fun. I decided to check for a spark in the ignition system. No spark on plugs, no spark on injectors, spark on coil. I used a bit of spray starter to verify it was not a fuel issue and it indeed did not start. I replaced the fuses and still no spark on them. I took off the Distributor Cap and am getting proper voltage to the ignition coil. There are 3 prongs on the ICM, 2 of which are reading 11.8v where the 3rd one is only reading 6.7v. Changed the Main Power Relay and verified it is getting power. Verified clip going to Distributor Cap is getting power. I am low on finances and plan to change the ICM next week but was curious if anyone else had any thoughts in the meantime. Strange to me that it was a bad fuel pump, replaced and started and now I am having an ignition spark issue.
Thanks for taking the time, I appreciate any advice.
