It also need air and spark. Cars need air/fuel/and spark to start. Check your spark plugs first. Also, when you get in your car and turn the key to the on position, can you hear a "hmmmm" sound? If so, this is your fuel pump priming and getting ready. If not, that may be the culprit.

Would a bad oil pressure switch cause a no start on a 98 b2500


Hi,
Symptoms of a bad or failing Engine Oil Pressure Sensor
  • Oil Pressure Light comes on, and you check the engine oil level, But oil level is okay, you can blame the false reading on the sensor.
  • Oil Pressure Light blinking constantly. This is the normal >check< oil pressure sensor Warning that the sensor is going out.
  • If the sensor is giving false readings, Dispite oil level, the sensor could be replaced.
If the Sensor is currently not working, and does not warn you of engine oil level, and oil level gets extremely low, The Engine could burn up/stall due to lack of oil, and may not restart.
Then you could probably blame it on the sensor.
But really would be lack of oil.

Intermittent No Start,
Common causes deal with 3 basic systems/areas of engin
  1. Compression, its the build up of air and fuel into the engines cylinders. Then is compressed by the pistons. And is under pressure. FAILURE An Air leak (vacumm leak) will allow pressure to escape.
  2. Ignition System, good battery, good relays, wires are not loose or disconnected, good 10volts to starter, 10volts to distributer>gives 20kvolts to spark plugs>has strong spark to ignite compressed air in cylinders. Other sensors need to work. Crankshaft sensor(ccs) Throttle Position Sensor(TPS), +more
  3. Air/fuel Ratio, Air Intake Manifold, and Fuel Pressure Sensor *Fuel Injection Pressure Sensor---if car is fuel injected*, air filter is clean and intake manifold hose, Throttle Plate Acuater, Idle Air Contro Valve(IAC). Also vacumm leak cause no start. To much air not enough fuel will cause lean fuel mixter==low power, low idle, no start.......To much fuel not enough air will cause rich fuel mixter==too much fuel could cause engine knock, flooding of engine wet spark plugs, No Start

I have overhauled engine for Isuzu bighorn 1998 petrol/gasoline engine. the 6VE1.timing belt is ok. Still it has a had start.


is this the Single head cam or twin version?
no photo of engine, so answers will be weak.

double posted. is this the single cam or twin cam engine?????? per side, the twin cam has 4 cams. 2 /bank.
i can not understand your questions, at all.
ok you overhauled the engine,
nor can i understand , still hard start.
does that mean it cranks slow and turn runs and drive perfectly ?
or cranks fast, but hard to start and runs perfectly?
or does that mean it cranks fast, starts, then misfires and runs crapppy-pappy?
hark, the devil really is in the details, no?

Generic answer.
all the wires and sensors , hoses not put back correctly.
oil full, coolant full, fresh gas in tank,
then you crank engine with no spark (I pull fuses)
and the crank it until oil pressure is good. yah, do that.

if really savvy, we check for top end oiling next. cranked only.


ok looks like oil pressure is good,(I don't want to wreck a new engine) (also check compression on a new engine, to see if we messed up., if not 150psi or more, you timed it wrong)



then we crank it, ok, it cranks and don't start
I check spark and it's timing using my timing light, it's wrong, i retime it, no and its ok. as is ..
ok sparks good, on all 6 cylinders. checked carefully and for static time.

so now start engine on test fuel,
if fails, see above for why.!
ok it runs for say 2-3 seconds and stalls. good.
We yell at the gas engine gods. O'BOY my engine seems to be OK ! progress....

next is fueling , ill stop now, as typing a book on fuel injection
is not easy here.
but fuel pressure is next. on all EFI engines. as is good fuel.
when did car last drive perfectly, 1 month ago,
10 years. what?
if long ago, the gas is bad. as are related parts all gunked up, like filters, and injectors.
and even the pump, or its sock packed in GUNK.
as you can see we have no history on the car, so.
really anything is possible. even vandalism.

btw we never just throw and engine in a car.
we check.:
1: compression, gee even sitting on a pallet.!
why install (6hr labor) a dead engine,?
2: then cranked oil pressure, spark/fuel off line.
same reasons.
3: then if all that is ok, I do check top end oiling now, if not any top end, the cams will not last very long. they will smoke and seize up in a flash.

this is how its done correctly, ask how.

Bravada starts fine but for short trips will not restart after turning engine off. Just cranks but wont turn over. Takes 3 or 4 tries then starts. Any answers?


I would suspect the problem is the fuel pump. It is located inside the fuel tank. Next time this happens have a spray can of starting fluid with you, spray it into the air intake of the engine and see if it starts right up, if it does you likely need to replace the fuel pump.

STARTING PROBLEM, WONT IDLE,BLACK SMOKE, ONCE STARTED IT SOUNDS ROGUTH


This problem is a bit more difficult to diagnose because half of your symptoms rule out half of the solutions. I would think the ISC control could be dirty or not working or your fuel injectors are sticking open.

With black exhaust smoke you are running rich. Often the "Cold start sequence" is at fault for poor starts making the engine too lean when the sequence fails. An intake air leak can cause the engine to run Rich, causing the black smoke, rough idle, rough running conditions. This is still a possibility, but the on-board computer usually sets a Code saying you are running "Lean" and then enriches the fuel ratio and floods the engine by itself.

Now the fuel injectors can cause several of your problems. For start-up problems, the remaining fuel pressure can dump fuel into the engine as the car sits because the injectors are sticking open. Someone would need to perform a fuel pressure bleed-down test to see if you have this problem.

Another way to verify this problem is to capture the oil during an oil change and smell it for gasoline fumes. The dilution of the oil will destroy the engine. If the injectors are found to be the problem, a new oil filter and change are needed.

95 f350 7.3 turbo deisel,truck is getting fuel wont start


I agree, please stop using the starting fluid. I don't know what you know or don't know but that engine has an intake heater and glow-plugs. Unless you disconnect those two circuits first, you could cause an explosion and damage the engine. The 7.3L is a good engine but there are a few things that can fail and not allow the engine to start but crank. I'm going to list parts to check: oil oil or oil that needs to be changed, blown fuses, over heated relays, fuel filter, fuel pump, damaged wiring to fuel pump, ICP censor, injection pump, IPR sensor, multiple worn out or damaged fuel injectors, damaged injector control module. You wrote that the engine is getting fuel. How do you know that. Please tell me what the fuel pressure is. Please write back if you have more questions and be as specific as you can. I don't know how far you want to go and what tools you have and what test you can run. Hope to hear from you soon, good luck.

2000 300m, car was running fine the all a sudden the oil light came on and the engine shut down. car will turn over but not start. oil light is on on the dash.


Either the oil pressure switch has failed, or you really do have zero oil pressure. The lack of oil pressure can kill the fuel pump to prevent a fire in a wreck.
You may be able to jumper the fuel pump relay to see it it will start, then figure out the oil pressure issue.

1990 buick century limited/ v-6 engine has fuel in the oil. need a fix.


could be a bad fuel pressure regulator. if they do fail, then it may result in low pressure. Mostly, the diaphragm in the fuel pressure regulator develops a leakage and the fuel enters the vacuum hose. This may lead to various kinds of troubles in the engine. Signs of a Bad Fuel Pressure Regulator
  • The vehicle engine runs rough and often stumbles and sputters.
  • The engine will not start after ignition. Usually, this problem is encountered in the morning when you start your vehicle. Many times, the engine starts, but stalls shortly after starting.
  • The fuel pump in the vehicle becomes noisy at times.
  • A bad fuel pressure regulator can also result in fouled spark plugs.
  • Last but not the least, the fuel mileage of the engine decreases noticeably. if above signs appear, replace fuel regulator. Check the oil dipstick and see if you smell fuel on it. If you do, it could be a symptom of a bad fuel regulator. The regulator has allowed gasoline to leak into the oil system.

Car will start,run for two good seconds and then die.can fuel filter be blown out? dont have the lunch money to get new one at the time.


no, its not a filter issue. Most likely a fuel pump issue. Spray brake cleaner to see ifit will run while spraying sparingly. If it keeps running then the fuel pump failed.

Engine oil light is showing on the dash board after switching on


Most important thing you need to do is to establish the actual oil pressure. put a mechanical gauge on the engine and read real oil pressure. If pressure is low (min is 15psi, I prefer to see at least 20 at idle) there is an internal problem...bearings etc. If pressure is good, sending unit has failed...replace it. I would not drive it 'till the oil pressure is verified as being safe. You might get lucky and someone just forgot to plug in the sending unit, but it must be checked!!!
good luck

Most likely it is oil smoke, if the smoke is black, and the check engine warning light is on, it could be over fueling for numerous reasons.How many miles on the engine?
