HELP! Whatelse can be my Start Problem?

sky2you · 02-17-07, 01:56 PM

Please Help!!

I have just finished the head gasket job by myself on my 91 Legend Sedan.
But the engine won't start.
I have checked the MAIN Relay, Sparkplugs, Ignition Coils and verified fuel pressure, there is fuel on the spark plugs. Timing belt is correct. Igniter unit is ok too. Actually I have verified actual sparks on all 6 ignition coils with spark plugs.

The only thing I didn't try is compression test.
Whatelse can be my start problem?

Does it crank?

Check every possible electrical connection.
I had a cranking only problem after a HG on my G1, looked around and found one small connector that wasn't plugged in. After it was connected, it started right up.

sky2you · 02-17-07, 02:14 PM

Yes, It crank and I have double checked every connectors. Every connectors are correctly connected.
No Engine Check Light on.

bump, bump!

i had a starting problem a while back, but i don't remember if it cranked or not... but I guess you can try this... put the car in neutral, push it a little bit, then try to start, if it starts it might be the starter switch, its very easy to change, i don't have a pic, but its like a 12 inch cable assembly with a white round thing at the end... hope this helps...

Ground wire on thermostat bolt?????????????

Jetdoc · 02-18-07, 12:38 PM

99% this is caused by something not connected. Things that can cause this: Ground wire at themostat housing not connected, ground wire on passenger side fuel rail not connected. Ground wire on passenger side valve cover not connected, Engine not timed correctly.

chingatorz · 02-18-07, 10:20 PM

I just wanted to apologize for the suggestion i made earlier... I was confused with the problem I had, it was actually the main relay that was bad. The starter switch problem came after that, and that had nothing to do with putting the car in neutral. I hope I didn't confuse you more than you already are.

CEL on?

fatjoe216 · 02-19-07, 02:21 PM

Make sure you have all your grounds hooked up as said earlier. I had the same problem. It was a bad ground from the main relay. When I would turn the key to the on position I would not hear the fuel pump and also the check engine light would glow very dim. When i repaired the ground wire it started right up. Good luck.

Did you change the spark plugs, or try to reuse them? You really need to look around the engine compartment and make sure you have everything hooked up, especially at the back of the engine.

Thank you!!
but I have double check the following ground wires and all wires are connected correctly.
themostat housing, passenger side fuel rail, passenger side valve cover.
Also I have checked the timing belt and it is correct.

And engine check light is NOT on.

But I have noticed that when I crank the engine, the "D4" light turned on about 1-2 sec. I don't know if it tells me something, I'll chek this on Legend manual (14-50).
Also I have noticed that when I jump the Service Checl Connector and turn ignition key on, the engine check light is steady on(no blinking or flashing).
I'll check this in Legend manual (11-34).

I didn't change spark plugs as they are just looks good to me.
Also I have checked the spark plugs and I could see the sparks.
(I don't know if this is correct way to test spark plugs but I just pull out spark plugs and ignition coil then conntect spark plug tip area and ignition coil's ground contact area near bolt hole to ground wire in passenger side valve cover's ground wire. Please correct me if I was wrong.)

Do you think I should replace the spark plugs even though I could see the sparks.

I did check entire engine area more than three time to see if there is any loose or disconnected wires but averything are connected correctly.

sky2you · 02-20-07, 10:45 PM

I have looked at the manual but nothing about D4 light(about 2 sec) when cranking.
And it is normal the engine check light stay on when service check connector is jumped.
Now I'm trying to check some sensors like MAP, ITA, TAS, TW....

Have you checked timing?
