Only cranks...

Rotary#10 · 11-04-2008, 04:48 PM

hey folks
i have a 91 n/a fc

the night i picked up my brother the car ran fine.. the next day i went to start the car it would only crank. i thought i was flooded so i tried to de-flood it and it didn't work. i tried pulling the egi fuse and cranking it. And i pulled the plugs and they were bad they did kinda smell gas. so i put another spare new set i have. I tried starter fuild but it didn't work.

still nothing what could it be ?

My oil is has bout over 850 miles
the plugs are new.
the wires are okie all plugged in
i have 12 volts on the gauge on the cluster

Are you sure you plugged all the wires back up correctly? The coil packs have numbers, like L1, L2, and T1, T2.

I woudl take off all the wires, and re run them one buy one. L1 goes to the bottom, T1 goes to the top, same for the second rotor.

Also, when you crank it, does it crank slow or fast? You want to make sure your battery has enough voltage.

How's the starter?
your fuel pump getting juice?

Lol, he did say it cranks, so I would assume that the starter is ok?

Phoenix7 · 11-04-2008, 05:49 PM

he did but it never turned over....

he needs to post a video....

Also, I like to throw this one in a lot....Check your main relay.

LOL all my fuses are good on the main fuse box in the engine bay.
the engine cranks fast and loud according to what Junpower heard on my celphone.. its odd..

im have to check tomorrow for

Air
fuel
spark

TehMonkay · 11-04-2008, 06:51 PM

Good idea, also check compression.

Rotary#10 · 11-05-2008, 06:07 PM

i checked the compression the poor mans way. it made 6 even chu chu sounds..( sounded like a chu chu train to me haha

) i know my motors good... im begining to think it maybe my starter. i checked a few forums about ' just cranking' ' no starting' a few were about the starter.. im pull it and get it tested and see what happens.

I do have fuel
and air.
i haven't checked for spark yet.. whats a easy way to do it?
i do recall at times a few times in the pass couple of months the car would crank a few times before it would start.. and the car did turn off on my twice when i was driving 2 different times when it was cold.. I believe that would be related to the spark plugs.

take channel locks with a rubber handle and wrapped in a t-shirt (or else shock) and hold each wire with the spark plug attached close to the fender while someone turns the key/tries to start the car
Best done at night or at dusk

take one of the ignition wires out and point it the nut or studs on the strut tower. crank away.
its easier if u can have someone help you.
where did u check if u have fuel? is ur afm hooked up?

Rotary#10 · 11-05-2008, 09:17 PM

i checked for fuel in the rear at the gas tank in the top of the sender unit. i had fuel in both the going to the engine line and coming back from the engine line.. i think it would be good to check at the block just above the filter. but i believe there is fuel in the lines.
my afm is plugged in.

RotaryXperiment · 11-06-2008, 08:19 AM

let us know when u check for spark

11-06-2008, 08:28 AM

Here is something I would try..

Remove the line coming out of the filter..

get a chunk of hose, put it on the filter, and put it in a bucket.

crank for 5 seconds and see if there is any fuel in the bucket.. (you may have to do this a couple times)

if no fuel the filter may be plugged, if not alot of fuel could be a weak pump or clogging filter.

then I would check for spark.. check on both the leading and trailing coils

quick side note if you take the starter off and take it to Advance, Auto Zone, O'Reilly's they test it for free

NoDOHC · 11-06-2008, 11:37 PM

Long story short, if the starter will turn the engine at a reasonable speed, it is not the starter. Just the same, you might want to pull start the car to see if higher cranking speed is all the engine needs to run.
