You said you have fuel pressure but what is it? It has to be 55 psi or it won't even try.

SOURCE: fuel leaking into vacuum line on fuel pressure regulator

If you have fuel on the vacuum side of the reg, that means the reg is leaking,causing a variaty of drivabiliy problems. Replacing this reg is very straight forward. Just add a little lube to the O-ring on the reg before installation. Good luck.
Yours Moe.

Car turns over but won't start. Boyfriend checked the spark plugs , says vetting spark. It says he did a compression check to it. Starter is a year old, battery new, we replaced fuel pump 3 weeks ago...


A thumb is not test for compression as 10lb/sq " will blow your thumb off. Have a proper compression test done. Next although it is sparking the question to ask is it sparking at the right time and to the right cylinder. Pouring fuel into the cylinder is a waste of time as the air/fuel ratio will be too rich to ignite even if the spark was occurring on the compression stroke. So here are some simple steps to follow to get it going
Have a compression test done to determine if there is sufficient compression to ignite the mixture
2 check that the spark is occurring at the cylinder at the right time ( no 1 cylinder on timing mark on compression stroke.)
3 . If it is EFI engine then check that the injectors are actually squirting if carby engine check that the fuel is in the fuel bowl With engines you have to have a combination of 3 things for the engine to work They are compression -which you will be checking for--2 spark timing--- which you will be checking for and lastly 3 fuel into the cylinder at the right time ==which you will be checking for
you only have to be missing one of these and you had best take it to a professional mechanic to get it started.

#2 cylinder misfiring why?


Usually if you know which cylinder, you check spark--fuel--compression on that cylinder.
You could do cylinder balance test, engine idling, kill each cylinder, one at a time. If you kill a cylinder that has no effect on rpms, that cylinder is dead for some reason, spark--fuel--compression?
I usually kill spark and do it quickly.

Engine won't start when hot


engine failed before pump, or after.. confused i am.

no matter, all gas engines work same. (in the global sense)
got spark?
the EFI cuts fuel if NO SPARK , by design (PCM brain logic programming) it tries hard to make that happen. (fire safety)

the rules for all otto cycle engines, in order.
1: GOOD compression on all cylinders, 150psi or more.
2: good spark on all cylinders. and timing. (its fixed time , year 2007)
3: good fueling,, not lean, not rich or flooding
the tests are easy, do you want to test or guess?

pretend that #1 is ok, many do. but pretend.
do not jump to #3, as no otto cycle engine runs with dead spark.

if flooded and spark is good, using a test spark pull.
use super secret WOT cranking, wide open throttle, this CUTS Fuel
on all cars, to clear a flood. its in the opr, guide that, on all cars.

Starter turns but does not start


what year car, what model and sub model and what engine.
lots of honda's from 1969(70'market) which one.?

no start, can be one of 3 basic things (generic answer ASE)
lost electric power to fuel or spark systems (Blown fuse?)
1: lost of compression 1 more more cylinders
2: lost spark 1 or more spark plugs.
3: bad fueling , too lean or too rich.

if you have spark times number of cylinders
then try test fuel, if test fuel runs car for 3 seconds.
then jump on why the fueling is dead.

My 1990 g20 van will not start , new injectors,fuel regulator,gets fuel has spark, turns over fine , what should i check ?


Is it sparking when and where it should? Checking timing. # 1 on compression stroke, Ignition rotor should be pointing at tab under distributor cap for wire that goes to # 1 cylinder. Line up timing marks on pulley as labeled or even at TDC for quick reference. With # 1 cylinder at TDC on compression stroke, rotor tab should be pointed at plug tab under cap, that goes to # 1.

Our 2002 vw gti 4 cylinder doesnt want to start. there is oil around the spark plug cylinder and the car turns over. We changed the crankshaft sensor a week ago due to it dying out, the problem actually...


Take the distributor cap off, crank the engine, see if the rotor turns.
Put it back together.
Remove the center ignition wire from the distributor cap, put the end of the wire within a quarter inch from metal ground, crank the engine, look for a spark.
The engine needs compassion, fuel, and spark to run. Check one thing at a time

Engine turns over but wont start? it has spark! and fuel!


Pull out # 1 spark plug and put back into plug wire, rest on motor block so that end of electrode is against metal. turn motor over and have a finger or compression gauge in # 1 cylinder, check to see if spark occur at same time as compression (compression will blow air past finger or raise gauge). When you say it has fuel do you mean gas tank has fuel? Are you sure fuel is getting to the cylinders? are plugs wet with fuel? Does it turn over but kinda thumps or backfire (Caugh)? Check the spark and compression first. if they don't happen at same time, the timing skipped or belt broke. if all is good pull plugs and inspect, could be flooded (WET) from fuel. either replace or spray with starting fluid and compressed air to dry them. spray starting fluid into air intake if starts then stalls, try again, if same thing happens then you have a fuel problem. try these suggestions first 1/2 hr time table, hopefully sucess, if not it sure indicates fuel.
