97 escort lx will not start, i have fuel spark and timing belt is good it cranks and sputters like its about to start but wont fully turn over every so often i can hear a pop sound when i try to start


Sounds like the timing belt has jumped some teeth. that pop you hear is detonation as the cylinder is firing while the piston is on it's way up.

1998 chevy 1500 silverado 5.7 z71 4x4 auto transmission Cranks wont start. The crsnk senser ok Has spark at coil Has good fuel pres I use start fluid thys to start What am missing Help


What engine does your truck have ? does it have The Central Sequential Fuel Injection (Central SFI) (4.3L, 5.0L, 5.7L) ? Is your fuel pressure with in (60-66 psi). if not , will not start . I find this a lot also fuel pressure regulators leaking will cause a hard start . https://youtu.be/09_wQ9yQ85A

2000 ford 4.0 explorer cranks but fails to start. It acts like it starts after sitting all night but then only cranks, what is wrong?


Check for spark to the sparkplug. Try a shot of starting fluid as having gas pumping and having the fuel injectors opening are 2 different things. If you have spark, then the fuel injectors may not be working. Quick diagnosis is to use starting fluid and see if engine tries to run. This indicates problem is not lack of spark but lack of fuel getting into cylinders.

No start has spark injector pulse, fuel, no codes


did you fix this yet, old post.
which engine, we cant guess that. ever.? (we know it's not a diesel)
if the engine has spark and fuel
and it dont start:
it's flooding? (spark tips soaked in raw fuel, ) we look at them......
did you try the operators guide trick, cranking with wide open throttle?
this cuts fueling , clearing a flood condition.
spec, is 120 to 150 PSI. 4.0L
or 4.7L?
good spark to ALL cylinders is the correct test, not just 1.
does the timing light show correct timing? cranking? spark timing?
ever do a tuneup, with new spark plugs yet.
If the above is true it will start. or at least on test fuel.

one way to find problems like this , if the spark is good.
is to cut all fuel injections. (i kill the fuel pump, ask how.)
and start car with test fuel, if it runs for 3 seconds each try.
then all is good , engine and spark, if not , not.
a simple test. that is. and works on all gas engines.

in this case he assumes the engine is good. and timed right.

I can run any engine, with no fuel in car. sure can.
and is safe to do.
use CRC.

Carcar dosent start


no starts.
cranks perfectly, full cranking speed, not 1 rpm but nearer 300.

ever do the 60k tuneup in the book.?
assuming the service was done and all cyl. are over 150PSI (WOT)
then we check spark first, not fuel..
The ECU brain cuts fuel (by design) any time spark is gone.
here is the proper flow:
1: throw, wild guess?, compression is good,. cam belt slip??????
is cam shaft turning,? look down oil fill hole. is it?
2: i check spark it's bad. (fix spark)
2a: i check spark its good', on all 4 cylinders not just 1.
3: spark was good. cam spins, pray compression is ok....
4: i connect scan tool, i crank for 5 seconds and see RPM rise ,good
i see ECT at say 50f (garage temp) and might see DTCs get thrown as i crank? , i see P0340 or p0355 ( one is dead CKP and other is CMP)
in my case no DTC thrown cranking , and i have spark and ECU
communicates. (key point) we alway s do that ,the tool is $9 (ask)

5: i then look at spark tips, they are:
1: soaking wet, its flooded, (spark was good but they are 10 year old.
2: dry, no fuel all spark tips day.
your engine has 4 cylinders, and all four most not flood or run dry.
i can listen to any cold start and hear gross misfire. but.....
if they are bone dry, i check voltage to the fuel pump.
it must be 12vdc cranking , 1/2 the cars you must crank. to get the pump to run ,(ECU hard logic!)
say I have 12vdc cranking
i check he fuel pressure, its not 30psi, its 5 psi (bad)
i rap the side of the fuel pressure regulator and it now is 30psi.
car starts. the reg was stuck wide open(its bad)
ok, still no start. or good pressure. Good is 30.
let say it was 60psi, i find i forgot to replace my dirty and packed up fuel filter
at the 60k mile service point. ( did i save $10 ? , no)
pretend filter is good..... pressure way low.... (examples)
so i read my FSM and it shows this shunt test, i then block (pinch)
the Fuel return line at the Fuel press. regulator.
i see 60psi, the pump is good. (do only for 5seconds ) (2 man test)
i see 10psi, the pump is bad ( of i have 12v at pump cranking,.....)
all this are pump tests there are 6 tests. not counting the injector balance test.

this is my order you can do it backwards, but will most the time have to start over, and cuss a $200 pump change , in vain.
here is the scotty way.

Example 2.
wont start, spark is good, tuneup done. sparks all 4 are wet
this is called flooding, the operators guide, says.
crank with the throttle open (WOT) car starts, it was flooded.
can happen in N.Canana (especially summer fuel in tank)
now car runs find and fresh fuel , 10 x better.
or no?
if no , post car keeps flooding, we can work that too.
is fuel pressure at 60psi, bingo, ask.

Suzuki vitara v6 will not start but engine check light comes on and i also changed the ecu


wow, you did it backwards, $$$$$$$$$$$$$$$$$$$$$
ever do the op guide lilsted tune ups at 60k intervals? miles>? if not why not?
did you try op guide stated WOT test, crank WOT, wide open throttle.
starts now (well it was flooded1) nothing, well, it's below.

watch scotty.
http://www.youtube.com/watch?v=064Ilsz8Fzg&NR=1&feature=fvwp

fuses good. battery at 12v not 10v. , fresh fuel, not 3 years old.
key on CEL glows.
cranks engine, cranks robustly.
you then check for spark. on all 6 COP coils. MUST WORK.
iS spark good or bad. .? ( all gas engines. not diesel)

good spark , yes,. try test fuel. (sold in stores,,,,,, in a spray can)
if test fuel runs good for:
no spark , attach any cheap scan tool, and crank for 5 sec.

http://www.fixkick.com/IGN_timing/no-spark.html#Cops

release key (not off) and see if P0340 or P0355 or close are thrown
YES, bingo and make sure RPM shows at near 300 cranking
if not, the CKP is dead.

A: 3 seconds each try, then the engine is good and so is spark if it sounds really good,..
B starts and runs, must have been flooded or no tune up ever.
C: starts and floods, again, and stalls, trouble shoot flooding.
D: Dead as a door nail. that means its:
1: bad engine, (compression way below 170psi)
2: or lost fueling. check spark tips , wet, is flooding or no spark.'
2a: or low fuel pressure, use a fuel pressure gauge.
0 or 2 psi bad, 20 bad, 30 good, 60 bad. 60 it floods. below 30 it starves. the FSM covers all pump tests, there are 6 tests.
there is also an injector balance test, if fails, the injector is dead or leaks all the time and floods a cylinder.

is this good, ?????
if not do you just want a simple guess?
ok my wild useless guess.
1: not ever tuned up;. "know today as, doing the service points''

1991 bonyville 3.8 starts and runs good, After it is driven for 20-30 minutes then will crank overe and aver but will not fire up. Leave hood open for 30 minutes and it starts right back up I have replaced...


Whe it won't start check to see if you have spark from one of the ignition wires. Typically when the crank sensor goes bad the car will stall as you are driving. If you have spark but the car will not start than the crank sensor is fine, Find the fuel pressure regulator located on the passenger side of the fuel rail. There will be a vacuum hose attached to the top. Remove the vacuum hose. Try to start the car. If fuel comes out of the pressure regulator where the hose was attached than the regulator is bad. If there is no fuel coming out of the regulator and you have spark try this. Turn the key to the run position, do not try to start, count to three. Turn the key off and then right back to the run position and count to three again. Do this 3 to five times. Then try to start. If it start right up you have a fuel issue and possibly the check valve at the fuel pump has gone bad. Good luck, let me know what you find.
