99 excoupe78

hello im new here but have a prob. my 99 ex wil not start i checked for fuel and spark has plenty of feul a the filter but spark is really light and sometimes not at all. i changed the distributer and coil and igniter. no change still does the same thing.. there is no engine light. any help would be awsome..

Check your grounds. Set a meter to Ohms and check the resistance between the valve cover and the battery negative post. The more resistance, the worse the connection. Make sure all grounds are tight. Did you have any problems prior to not being able to start? Any engine mods?

if you say you changed the distributor, then it should have all come with the coil and ignitor, so did you put a while new distributor on, or did you just change coil, did you check the ignition control module, inside the distributor, and did you change the cap and rotor, and wires as well?

99 excoupe78

yes it seemed to have a big lack in power and that day had a missfire all theway home before dien in my driveway. it retasted but idle real low an rough before shutting off and not restarting.

99 excoupe78

yes i put a brand new one in it had everything inside it.cap and rotor i changed the other day and wires and plugs a few months ago. mods r exhaust intake.

Since replacing the distributor, have you again checked for spark? It should be bright white at all four plugs.

99 excoupe78

replaceing the distributer changed nothing still very faint spark mostly no spark at all. every few cranks u see a little spark but nothing like it should be

With the key in ON(II), what voltage do you measure at the Blk/Yel wire attached to the coil and ICM.

What are the resistance measurements on the new coil?

Is the timing belt stripped?

99 excoupe78

i checked the top half of the belt it looked good. also lined the motor up to dtc and it lined up perfect.. ill chime back in with my findins on the voltage at the coil..

99 excoupe78

12.35 volts

Test the coil:

99 excoupe78

i got 0.09 between the a and b terminals..

Former User

There's two resistance measurements. Which one?

99 excoupe78

i got 0.09 between the a and b terminals and 17.8 between the a and winding terminals

Former User

You found the problem. The coil is toast.

99 excoupe78

really. the distributer cam brand new with igniter and coil.. autozone crap i guess.

Former User

This^ or you cranked the engine with one or more spark plug wires unplugged.

99 excoupe78

nah everything was in place when i attemp to start.. thanks alot

99 excoupe78

ok well update on my ek. i have taken back my new distributer and replaced with a different new distributer. i have replaced so far, cap rotor wires and plugs and the distributer twice and i checked the belt it is lined up. i have replaced the main relay.

Former User

The engine still cranks but does not start, right? Go back to basics. Have you checked for spark and listened for whether the fuel pump primes? Any CEL codes?

nahnah05

i know some of the civics have an inertia switch that cuts off fuel. that might be worth checking too

Did you ever end up checking your grounds as suggested?

99 excoupe78

yup now i have 0 spark and my fuel pump kicks on. i cracked the 17mm loose at the fuel rail. and no cel..

99 excoupe78

yes i did but forot to post my numbers. i will do so again.

Former User

If you had a ground problem, the fuel pump would not work.
