Sounds like the timing chain let go on you. You have fuel, you have fire, nothing really left, but to, get them to meet at the right time. Take the distributor cap off, turn the engine over, and if the rotor don't move, then you will know the chain went. It is possible that the chain could've jumped a tooth or two also, but I'm almost possitive that it broke. I sincerely hope that I could help. Good luck and best wishes.

    Try the camshaft sensor. If it went bad, you would have no spray out of the injectors. Hook up a noid light to an injector connector to see if you get any + pulses, while cranking the engine. I almost guarantee this one.

    I take it, that the camshaft sensor worked? I'm dying to know what was wrong. Take care.

  • Bryon Agin Jan 25, 2009

    Thank you for rerating me. Was it the camshaft sensor? take care and God bless.

I have a 1987 ford ranger the engine turns over but it wont start


Spark at plugs? Fuel filter? Pressure on injector delivery line? Pressure relief valve? You may be able to measure fuel pressure at the pressure relief valve location. and return line. If you have spark, I'd say it's a fuel supply problem

Tip

Fuel systems on cars


2) Fuel: From tank to engine

The modern fuel tank is fitted with a sealed filler cap. Set within the fuel tank is the fuel level sender which sends a signal to the fuel gauge indicator on the dashboard. Fuel is drawn by a pre-pump (lifter pump),also within the tank, through a filter 'sock' or strainer to prevent bulky debris rom entering the fuel line; the pre-pump maybe located outside but near to thefuel tank. Also connecting to the tank is the fuel return pipe and often on top of the tank can also be found a pressure sensor. Associated with the tank there is often an expansion vessel to accommodate thermal expansion of the fuel. Finally attached to the top of the tank, or top of the expansion vessel, there is a fuel vapour recovery pipe that is part of the evaporative loss emission control system employed to prevent fuel vapour release to the environment (see later in this series).
Fuel is pumped from the tank by the pre-pump through the fuel line towards the engine: on some systems a further 'main' fuel pump may lie between the fuel tank and engine. The fuel, now under considerable pressure, passes through an in-line fuel filter that removes any fine particulates before they reach the engine. A clogged fuel filter puts a strain on the fuel pump so routinely changing the fuel filter can help prolong the pump's service life. On reaching the engine compartment the fuel line connects to the fuel rail mounted on the engine. The injectors feed directly off this pressurized fuel rail. Mounted onto the end of the fuel rail after the injectors is the fuel pressure relief (FPR) valve which governs the fuel pressure in the line all the way back to the fuel pump(s).
The critical component within the FPR is a spring loaded diaphragm whose role is to maintain a constant force on the relief valve. Fuel, pressurized by the action of the fuel pump, is forced against the valve and excess pressure allows fuel to bleed past to the return fuel line back to the fuel tank. Attached to the top of the fuel pressure regulator is a vacuum line connected to the inlet manifold. The vacuum partially offsets the action of the diaphragm spring. When the engine is at idle, the throttle plate is closed and the manifold vacuum is at its greatest (lowest pressure), the strong vacuum sucks back on the diaphragm against the spring pressure allowing a reduction in the fuel pressure needed to open the relief valve. This reduction in fuel pressure helps minimize fuel consumption per each injection cycle when at idle. Conversely, when the engine is running at high speed, the throttle is wide open creating little or no vacuum in the plenum. This reduces the pull back on the FPR diaphragm and consequently the fuel pressure in the fuel rail is at its highest.
In 'common rail' designs the injectors are controlled by the ECU. The ECU controls the injection cycle time (pulse width) and, in very modern systems, the actual injection pattern. When the car is at idle the injection times are short and when under load the injection times are longer. Similarly when the engine is cold (as indicated by the engine coolant sensor to the ECU) the injection times are longer to ensure a richer starting mixture. The combination of injection time, along with the fuel pressure in the fuel rail, dictates the engine speed and fuel consumption.
In recent years evaporative loss emission control systems (EVAP) have been introduced to prevent the escape of fuel vapour from cars. The fuel vapour that evaporates from the surface of the fuel in the tank is conveyed by the vapour relief pipe to a charcoal filled canister. The fuel vapour is stored in the charcoal for later use by the engine. Access to the stored vapour held in the canister is controlled by electrically operated valves. When the engine is cold the charcoal canister purge valve is kept closed. At normal operating temperature (signalled from the coolant temperature sensor to the ECU) the purge valve opens allowing the stored vapour to contribute to the air in the inlet manifold. The charcoal canister also has a vent valve operated either electrically or passively, in response to internal pressure drop, which when open introduces fresh air to help flush residual vapour out of the charcoal canister.

I had a Denali that did the same thing. I put a fuel pressure gauge on the fuel line test port up at the engine. Turned on the ignition and got a low fuel pump pressure reading. Replaced the pump and pressure went back up to about 62psi. If the relief valve is bad it will probably do the same thing. I've never heard of a relief going bad though. Good luck.

How do you change a fuel filer on a 1997 olds achieva


FIRST OF ALL RELIEVE THE FUEL SYSTEM PRESSURE.RAISE AND SAFELY SUPPORT THE VECHICLE ON JACK STANDS.USING A BACKUP WRENCH REMOVE THE FUEL LINE FITTINGS FROM THE FUEL FILTER.FOR THE LINE DISCONNECT SIDE OF FUEL FILTER. SQUEEZE BOTH TAB IN. SO YOU CAN REMOVE FUEL LINE FROM FUEL FILTER.REMOVE THE FUEL FILTER MOUNTING SCREWS AND REMOVE THE FILTER FROM THE VECHICLE.REPLACE THE O RING WITH A NEW ONE LUBRICATE O RING WITH A LITTLE ENGINE OIL.TIGHTEN FUEL LINE TO FILTER CONNECTORS 22 FT LBS. THE 2.3L ENGINE RELIEF FUEL PRESSURE LOOSEN FILLER CAP.REMOVE FUEL PUMP FUSE LET ENGINE IDLE UNTIL IT DIES FROM LACK OF FUEL.THE 3.3L ENGINE RELIEF FUEL PRESSURE BY INSTALLING FUEL PRESSURE GAUGE TO THE FUEL PRESSURE TEST PORT WHICH IS THE SCHRAEDER VALVE WITH CAP.ITS ON THE FUEL PRESSURE REGULATOR ASSEMBLY.USE A SHOP TOWEL AROUND CONNECTION TO CATCH FUEL SPRAY.YOU CAN USE A SMALL TINY SCREW DRIVER AT PORT ALSO BUT COVER IT WITH TOWEL TO CATCH FUEL SPRAY.WARNING GO TO DEALERSHIP TO BUY O- RING THAT GOES ON THE FUEL LINE TO FUEL FILTER.IT LOOKS TAN.TAKE THE OLD O-RING TO GET THE CORRECT SIZE O- RING TO FUEL LINE TO FILTER.DONT USE ANY KIND O - RING GASOLINE WILL DISSOLVE IT YOU WILL HAVE A MASSIVE GAS LEAK.WHEN YOU FINISH PUTTING NEW FUEL FILTER IN PLACE ALL FUEL LINES CONNECTED.MAKE SURE WHEN YOU INSTALL NEW FUEL FILTER YOU HEAR OR FEEL THE DISCONNECT SNAP IN PLACE ON THE FUEL FILTER.PULL IT A LITTLE MAKE SURE ITS IN PLACE.WHEN ALL FINISH AND DONE.TURN IGNITION SWITCH ON POSITION ENGINE OFF 3 SECONDS CHECK FOR LEAKS.IF YOU GET LEAK FUEL LINE O - RING LEAKING BECAUSE TOO BIG TOO LOOSE OVER TIGHTEN DAMAGE O - RING.

It sounds like the fuel strainer is clogged or one of the filters is clogged. start by taking the fuel primer pump and attempt to prime system if the pump handle sucks back down when you attempt to pump there is a clog in the system. There is a lot of water in diesel fuel and they build up algea over a number of years and generally the fuel strainer(part at fuel tank that the feed line attatches too) clog up. you can remove them and clean them. Good luck

Car dies when accelerate. do i need new fuel pump?


Hello;
It sounds from your description that the fuel pump is weak. To check the fuel pressure you need a fuel pressure test gauge for fuel injection. Attach the gauge to the test port schrader valve and turn the ignition to the on position. Record the reading. Now start the engine and record that reading. Unplug the pressure regulator vacuum line and record the reading.
The pump should have pressure with in specs but if low, start with the installation of a new complete pump. It is located in the fuel tank. Also replace your fuel filter.
Hope this helps you.
Thanks;
Rich

1992 pontiac boneville, keeps stalling


Have you chg.fuel filter and had a fuel pressure test done? Does it have spark after it stalls? Fuel pumps are a common problem, they work when cold get warmed up they quit, after a while quit all together. Do the fuel pressure test.

1997 buick le sabre


its the electrical connection at he fuel pump,if this is ok ask if they replaced the strainer on your fuel pump,your fuel pump is inside your gas tank ,you have to drop the tank to service,most fuel pumps are not warrantied if you dont change the strainer,when your car shuts off the sediment on the strainer falls back into the tank,but when you run your car and it sucks up the gas thru the strainer to the pump it clogs the strainer and the fuel pump cant pump,you shoiuld find out if they changed this because your forcing your fuel pump to work harder,was it a new fuel tank or used one that they put in
