93 Honda civic no start!

[s59614e]

Hi every on my name is Gordon and this Honda is my son's college car!
well lets start at the first!!!!!
I wrecked my Honda 6 1/2 years ago and just got the body work finish last week!

I gess i should explain the crash first! Big farmers fork lift when thru the hood, thru the valve cover,drivers side strut tower,wiper arms, and windshield! (missed the block on my shoulder's tho )

now i have replace the valve cover(lucklly it didn't touch the valve train!) my body man did the rest and the car.

just will not start,turns over just fine, but will not start!

sprayed carb spray and it will start and die!
check fuel pump and there was flow but no pressure!
replace the pump to night and now i have a lot of pressure but still no start.
check the spark plug wire for spark(i know, if it will run on carb spray it has spark)
check fuel at fuel rail and it had pressure there also check the inj. wires and thay have 12v (will light a test light!)with the key on but now ground with key on, with eng cranking.
Have checked all the fuses...that i now of with a test light and thay are all good! (the box next to the battery and the fuses under the steering coulmn......any ether ones???)

What sensors tell the computer to fire the injectors????

is there a hidden fuse next to the computer or a crash sensor....like Ford uses that need to be reset?

O ya i allso drained all the nasty old fuel out of the tank while i have replaceing the pump.......Has 5 gal fresh fuel in it!

The ECU uses the same signal from the distributor for both spark and injector opperation. Inspect the wire harness to make sure rodents haven't been chewing on it. Look for signs of corroision at harness connectors. Make sure the connectors beneath the underhood fuse box are not loose. Look for corrosion at the ECU connection plugs.

justsaygo thanks for the ideas!

alltho the car has been garaged all of it 6 1/2 years the rodent idea was a good one

remove bat, fuse block and cover beneth it. remove ECM and wires to it.......the one in the right or passanger side side kick pannal, right?

well theres no damaged wiring or corrosion there!!!!

Do you now which wires coming out of the ECM are for the inj.so i can test for ground pulse there!
or better yet dus any body have a pdf file for the wiring scamatic?
is there any thing els that the computer look at before it deside to fire the inj.?

Found i guy on this sight, that hooked me up with a sight that sell FSM so when it gets here i will have a wiring diagram to go with but will take several day to get here and would love to have fig it out before then.

has any one had this type of no start that could advice me or has a FSM that could give me the pin # or colers of the injector wires going from the ECM to the injectors.

Hi, I was wondering if you had found your problem or not. I am having the same kind of problem. Thanks, Ted

I have a 1991 civic and I pulled all the fuses out that were under the hood and then put them back in, it reset the ecu and was fine
