I have this del sol and i drove it from college 4 and a half hours away and parked it friday when i went out saturday it would not start. Tried to pop the clutch and it did not work. The engine turns but will not turn completely over. has no fuel pressure i have replaced both the fuel pump and the main relay i am lost on where to go if i run a wire from power to the pump it will pump. my battery is good and my lights and everything work. The engine just won't complete turn over and start and has fire through the spark pugs. If anyone would please help it would be a lot of help. thank you very much.

Unplug ECU connector A.

http://www.phearable.net/tech/wiring...schematics.gif

Turn key to ON(II).

Ground ECU connector terminal A7 or A8 (Grn/Yel wires) to the metal frame under the dash.

Does the fuel pump run?

 

Borrow a known good ecu. Probably a burned out capacitor on the ecu circuit board. C14 maybe.

 

where is the connector A i cannot find it?

 

Click the link.

 

im sorry that was poorly worded on my part i don't know where the ecu to undo connector A

 

Behind the front passenger kick panel:

 

Thank you i will try this when i get home from work at 2:30 and let you know thank you again for helping

 

Alright I did what you asked and it didn't turn the pump on but like i said i have replaced the pump and if i run a power cable to it it comes on. i went ahead and took the ECU out while i was there while trying to start the car it sounds the same with or without the ECU plugged in. Does this mean my ECU is bad? and when i opened it up some of the capacitors were brown around them i took pictures but can't figure out how to put them on here. Thank you again everybody.

Unplug the main relay.

In the main relay connector:

Terminal 1 = Yel/Wht wire (voltage from 15A hood fuse 31)

Terminal 5 = Blk/Yel wire (voltage from ignition switch via 15A dash fuse 24)

Terminal 7 = Yel/Grn wire (to fuel pump)

-----------------------
If you short terminal 1 to terminal 7, does the fuel pump run?

If you short terminal 5 to terminal 7 and turn the key to ON(II), does the fuel pump run?

 

if i short terminal 1 to 7 the pump runs and if i short terminal 5 to 7 with the key on the pump does not run. This is all with the edu plugged back in.

 

Check whether 15A dash fuse 24 is blown.

 

the fuse was blown so i replaced and tried to start car again with everything hooked up and it did not work but also did not burn the new fuse

 

Redo these two tests:

 

when i did this test again it sparks and the pump comes on?

 

ok when i do both tests they both give a small spark then the pump kicks on

 

Now redo this test on A7 and then A8:

 

ok when i ground both of them the pump comes on.
Thank you again, Dustin

 

If you plug the ECU connector back in, does the engine now start? If not, your results are pointing to a bad ECU. If you have a multimeter, there are additional tests that can be done to verify this conclusion.

 

alright thank you very much

 

Alright i tried to by pass the grounding through the ecu and ran a wire out of the plug to the chassis and the pump comes on then i try to start my car and it still doesn't start are there any tests i could do to verify that it is the edu with a test light or jumping wires?

 

I can't help you with this^ because I don't know exactly what you did. Is there bright white spark at all 4 spark plugs?

In addition, you don't want to bypass either the main relay or ECU. The stock arrangement serves as a safety feature to reduce you chance of dying in a car fire following an accident.

No. You need a digital multimeter. You can buy one for about $4 from Harbor Freight Tools.

Do you have a friend who will let you borrow their Civic ECU?

 

Yea all the spark plugs spark with no problem and if i get a multimeter what are some of the tests i can do?

 

Bright white spark?

What exact test did you do? Details?

Get a multimeter, and I'll post the tests.

 

I pulled the spark plug and used the spark plug cord grounded the plug to the motor and cranked the car over ad all four spark plugs spark white I just replaced the distributor this summer the whole piece is new and I am going to get a multimeter right now if you could post the first test? Thank you very much
