Why is FD46 engine unable to start after complete overhaul?


The camshaft timing may be correct but is the ignition 180 degrees out so its firing on the exhaust stroke?
Check this by watching the valves on no1 cylinder and when they are both closed see if the timing mark on the crank corresponds to the firing point on the distributor

No start after new cylinder heads and timing belt


Recheck your timing you might have it 180 out

Timing correct firing off


what engine Shawn. ? how can we guess that?
besides following the FSM steps, we could:
ive rebuilt many engines (done many from scratch) +machine work.

1: I check compression 1st. on all cylinders. (i put oil in the cyl, 1 teaspoon) (some pros run oil gallery primers pumps first in pro rebuild shops) i just crank the zero fuel engine until i see max oil pressure.)

oops. ? no oil pressure, oops, compression bad. on 1 jug.
(all that good, so)
2: i then crank it over , with no spark or fuel and check for top end oiling. Valve covers off. (so those V.C go on last)
ive watched many an noob burn up a new engine, not doing the steps in the rebuilders books. it only takes me 30min. to do this. why skip it.?

3: ok , I got top end oil, got 150psi on all jugs. (hard work pay back)

4: i check for spark all cyl. it's strong, & out comes the timing light.
oops, timing is off, or spark wires routed wrong, (dizzy engines)
i check all cylinders for hot spark and #1 timed right. and routed right.
the strobe light never ever lies to me....

MILESTONE 1: TEST FUEL moments.
5: wow ,car runs on test fuel (spray can, CRC engine start with top end lube feature) (fuel pump is shut off on purpose , in all steps to here)
i repeat this say 3 times, listening carefully for noises, that are not good. (why start the engine and watch it blow up. )
It is so good, to hear it run for 3 seconds,, wow.
im 100% sure you can get here..... if you do the steps.
Now comes, light the fires and kick the tires. not FIRST.

6: now comes fuel
how to get fueling to work.
that takes understanding the ASD and how to use a $1 NOID lamp.

I check injectors then add fuel pressure.
are the injectors firing?
injectors ,click cranking ?(stethoscope tool $5)
if not, use the NOID, is the PCM firing the NOID? y/n?

why do this , with pump dead.
Answer to not wreck your new rings, all washed free of all oil buy
injected, unburned raw fuel .. that is why.
i get all my injectors firing then , turn the fuel pump on.
its your hard labor, 50 hours? to build and engine?
wana waste all that? nah.
I last , plug my fuel pump back in,
does the PCM start enging for 2 seconds, and then cuts fuel?
BAM ASD.

ive never burned up a new engine, yet,
im not lucky, or smart, just had good teachers.

jeep ways!
I kill my pump by pulling the pump feed wire.
i do that because some newer jeeps , kill everything (ASD) including spark,
if you pull the fuel pump relay. (jeeps with new pump monitor features)
so i cut the feed AFT of the relay, on all cars. (conn. pulled)
the FSM shows this spot.

hope that helps.

2006 hyundai sonata takes awhile to start


Could be a fuel problem. I would have someone check fuel pressure before and after cranking the engine. You may be loosing some fuel pressure back into the tank when the engine is off.

1988 Chevy S10 Durango Pickup, Won't start will fire


sounds like ignition module inside of distributor cap under distributor rotor button.these do go bad and can easily be replaced.strong suspicion from your details that this is the culprit.

Hard starting, excessive crank time


try changing the fuel filter and turn the key on and off several times before starting engine. once running check the vaccum line on the fuel pressure regulator.the regulator can leak fuel from that connection.

sounds like a poor connection on the battery. Check the posts (take off, clean, etc). If that doesn't work get you battery tested.
