You have pressure in the fuel lines and it doesn't start you put fuel in the intake manifold and it starts Bad fuel pump?
If you put fuel into the intake and it starts and keeps running, replace the engine coolant sensor. If you put fuel into the intake and it starts but stalls it probably is a bad fuel pump or pressure regulator. Do a fuel pressure test. Need to know what model, year and engine you have to help you any more.
What else can I help you with?
On a 1989 S10 Blazer where does the 4x4 vacuum hose start and end?
IT starts @ the intake manifold & ends on the front axle.
Does a 1991 Mazda Miata have an EGR valve?
Yes, on the back of the intake manifold. If looking at the engine from the front of the car, the large metal piece connected on the left of the engine is the intake manifold. At the back (towards the firewall) of the intake manifold is the EGR valve. With age, it typically starts looking a rusty red and is held on by two bolts and an electrical plug.
2500 350tbi when you idle sometimes the engine dies but when you put gas in carb tbi it starts whats up?
Well you might have a dirty fuel injector, low fuel pressure, or an air leak somewhere in you're intake manifold.
What are the intake bolt torque specs and sequence for a 3.8 Mercury Cougar?
For a 3.8L Mercury Cougar, the intake manifold bolts should typically be torqued to around 15-20 ft-lbs, but it’s important to consult the specific service manual for your model year for precise specifications. The torque sequence usually starts from the center bolts and works outward in a crisscross pattern to ensure even pressure distribution. Always follow the manufacturer's guidelines for torque specifications and patterns to avoid damage to the intake manifold or engine.
Where is the air intake on a '93 Honda Civic?
It is located on the passenger side of the engine compartment. There is a black intake hose that starts at the intake manifold(back by the firewall) and runs down to a black box which contains the air filter(up front by the passenger side headlight)
Why an intake pressure boost in a two-stroke engine is a must?
After the exhaust blowdown is nearly complete, the intake slot starts to uncover. At this point an intake pressure boost is needed to increase the pressure at which the air enters the cylinder, to push the remaining exhaust gases and fill the cylinder with combusted air-fuel mixture.
A Jeep Cherokee classic has occasional idling problems when its cold it starts but doesnt want to idle until it reaches normal running temperature and the problem is sporadic what might be the cause?
Intake air temp. sensor on top of intake manifold near the throttle body. Two wires. Will sometimes throw an engine code, which is removed by disconnecting negative battery cable end for 30 secs or so.
Where is the intake plenum on a Toyota engine?
The intake plenum on a V-6 or V-8 is bolted to the top of the intake manifold. It has the throttle body bolted to it. The throttle body houses the throttle plate and is located at the end of the tube that starts at the air filter housing. Sometimes the intake manifold on a 4 cylinder is referred to as a plenum. It works the same way and is found in the same manner. Look for the air filter housing, then follow the hose past the throttle body to the intake or plenum.
What causes gas in the oil on a 350 engine?
If it runs fairly normal once it starts and you're getting fuel into the crankcase, it's PROBABLY a leaking injector. After the engine is shut off there is still pressure in the fuel line. If the injector leaks, fuel will drip down into the intake manifold. If a cylinder has an open intake valve, the fuel will leak into there and find it's way into the crankcase.
Where is the cold start valve on a 1988 Mercedes 300se?
The cold start valve on a 1988 Mercedes 300SE is located on the intake manifold, near the throttle body. It is typically positioned on the side of the manifold and is connected to the fuel supply and electrical harness. This valve helps enrich the fuel mixture during cold starts by injecting additional fuel into the intake manifold. To access it, you may need to remove certain components for better visibility and reach.
93 z24 turns over but won't start?
This sounds like a fuel pump issue, an easy way to check this is to spray a flammable liquid in to the intake manifold just in front of the throttle body, if the engine starts for a short time then dies it is not getting fuel. A safer way to do this is to get a fuel pressure gauge and test the fuel pressure. most newer vehicles require at least 55 PSI or more fuel pressure to start
Where is the cold start injector valve on a 1988 Pontiac fiero?
The cold start injector valve on a 1988 Pontiac Fiero is located on the intake manifold, typically near the throttle body. It is designed to provide additional fuel to the engine during cold starts to assist with ignition. To access it, you may need to remove a few components around the intake manifold for better visibility and reach.
