RRC- Turns over, Won't start

[luvs2getmuddy]

Ok, after my new Fuel pump(hard wired), full tune up, Re-charged battery, and lots of good fuel in the tank, RRC won't start.
It turns over. But won't catch. I tried moving the distributor while turning over to see if it'll catch, it won't. I have spark and fuel, what could it be???

Next things to change with working spares will be Ign coil, and TPS.

Any ideaS?

If you have good spark, don't screw around with the coil.

It should start without the TPS even connected, won't run well, but should start.

Pull the number one plug and set timing.

I had similar problems with my 1995 classic. It looked like I had good spark at the plugs. Timing looked ok also. Went throught the trouble shooting in the manual and discovered the distributor rotor leaking energy to the shaft. I went with a lucas rotor as every aftermarket type failed shortly after install. I keep a spare in the truck ALWAYS!

I AGREE
i always use ome ignition parts, the after market stuff
is junk.

I just had a full tune up done with whaqt looks like OEM stuff from a local indie.

I am thinking the chan skipped a lot.(it has skipped before)

check the ignition module next to the distributor...mine was bad but gave me spark....it caused the timing to be off until it was replaced.

May want to check your exhast. I encountered a situation where the truck would not start but would turn over. Unbolted the exhast and it fired right up.

That sounds awefully strange!
Would a plugged/damaged catalytic cause that?


Well, we are clueless.
The trucks electrical seems to be fine. It has power to the injectors. It cranks over, but won;t catch. Several times, for a split second, it sounded like it might catch, but didnt.
Tried a different ignition-distributor module, which made things worst(no spark). Tried different coil, and tried spraying ACE starting fluid to see if it'll catch. Nothing. We are stumped....

 

[barefoot]

have you checked timing?

tried to swap out crank sensors with someone?

 

[singingcamel]

whats the spark like from the coil? have you checked that? snappy blue!
check all your plug wires from the dizzy cap, checking firing order. try your old rotor, and cap.
pump running with the key on? getting fuel to the rail?

 

[luvs2getmuddy]

I think the spark is sufficient?.
How do you check the TPS?

:banghead:

If it has a distributor, IT DOES NOT HAVE A CkPS!

If it won't start with ether poured down its throat, it is either timing, cam wear, loss of compression, etc.

Check the damned timing!

good post just recently,Checking efi just down(below) ..

 

[luvs2getmuddy]

I really appreciate your input.
Ok.
Lets start at the basics. You are right, no CPS. TPS should be fine.
I have spark. I have tried 2 different ignition coils. I have new rotor/ cap. New wires. New plugs. I am not sure HOW strong the spark is, but my indie says it should be enough to get the truck running.
When Spraying ACE in to it, it still doesn't want to go. It 'popped" or seemed like it may catch a few times for a split second, but didn't.
Apparently my injectors are getting power- how strong their spray is, i am unsure(can they be so dirty and not spraying enough?). My fuel pump has been hard wired, so I AM getting fuel otherwise.
He has checked the timing on two cylinders and says that it is fine. I have told him to RE check it.
My compression is strong on 6 cylinders (120-150), and low on 2 (5/8)- 50psi and 80psi.
The motor spins freely so there is no internal damge it seems.
We tried moving the whol;e distributer while cranking and nothing.

We had something very similar, and very strange, happen to our RRC once. Everything checked out (plugs, ignition coil, etc etc) but it finally had to be almost flooded. Something was either clogging the fuel line (we promptly changed the filter) or there was some bad gas that wasn't getting through. It was weird and took almost two days of checking for us to try and just floor it when starting! DUH!

 

[crown14]

yeah you need to check fuel flow

and that low compression on 5 and 8 is not good

Hi, Sorry to here about your Rover. The two bad cylinders is'nt good but probably not your problem.Have you checked the fuel pressure at the rail while cranking? How about the voltage to the ECU also while cranking? I also like to pull several differant spark plugs ( one at a time ) and see that the spark is actually getting to the tip. You need to be very careful with starting fluid! That being said, try using it to see if it will start and run with you giving it shots of the stuff to keep it going. If it does not start, don't bother with the fuel system yet. You have a electical, ignition, or both problem. Was the distributor "pulled" and put back 180 degree's off? Good Luck, 4Runner

Hey, the exhast was clogged and created back pressure so the engine would turn over but the plugs would get wet and we would have to wait for them to dry. Finally took off the exhast behind the y pipe and the engine cranked over fine. You can see a great example of this problem in the movie Beverly Hills Cop where they stuck a banana in a tail pipe

If it pops but won't start then it sounds like timing.

Check firing order of your plug wires on the distributor cap. I once put mine on backwards on my series III and the thing actually started. It ran like crap but it ran. I diagnosed that thing every which way but loose and when I was just about to tear into the timing chain, I thought I would check everything once more and that is when I found my stupid mistake. Once I put the plug order right she ran like a champ.

Remember when trouble shooting...90% of the time the answer is in the assumptions we make. Recheck all the "givens" and then go forward.

 

[luvs2getmuddy]

just a quick update.
The truck was severely flooded.(how or what, don't know)
It will fire up now, with ACE starting fluid.
I have decided to spend some cash and rebuild the top end, and fix the bottom end(due to the low compression in two cylinders.)
Looks like no wheeling for me this season.
