Re: E300 sprodic starting
When you get this kind of problems, you always start replacing plugs, and eventually air filter and fuel filter if they are dirty. Once you exclude this simple causes, usually is either an injectors problem, or an ECU problem. ECU is the computer that controls electronic injection and often is cause for the problem. YOu cannot test or fix the ECU at home, it must be connected to a machine that controls computer and check fuel flow at the same time, you need to do this in a garage. Start doing the simple things, and eventually go to a mechanic if problem keeps going.

Without knowing more about what you are working on it is very hard to say what the problem might be, but if you have fuel to the rail but not into the engine it would have to be the injectors not opening. I would think to check the ignition pick-up or the crank sensor.
Check spark plugs and eventually replace air filter. Is it an injection or carburetor model? If it injections it is probably a dirty injector or a computer problem. If it is carb you need just to regulate carburetor.
P0216 DTC - Injection Timing Control Circuit Malfunction and this means the diesel fuel injection pump has a timing failure. This could be that the injection pump timing needs adjusted OR the failure is internal to the injection pump and therefore non-adjustable.
NOTE: If your vehicle is a Dodge Ram with Cummins engine then be aware that fuel delivery problems frequently cause this code. Prolonged fuel delivery problems can cause injection pump failure!
Symptoms of a P0216 DTC may include: Low power Crank, but no start Hard start Displays an intermittent stumble or miss Engine may start and then stall Engine may appear to drive fine but surge at idle
The most frequent cause of this code is a bad injection pump due to poor fuel delivery. Fuel delivery problems could be: A plugged diesel fuel filter An in-tank blockage Air in the fuel due to a cracked in-tank fuel ine above the fuel level Bad transfer (lift) pump Injection pump out of time
Possible Solutions: First, simply check if your injection pump timing is adjustable. If so, check the timing and adjust if necessary.
If you think that you may have a fuel delivery problem, then check the lift pump operation. On Dodge Ram with the Cummins engine, the lift pump should produce about 45 oz of diesel in 25 seconds of operation. This can be performed by disconnecting the fuel hose from the injection pump and pumping the fuel into an approved container. Bump the engine over but do not start it. Then the lift pump will operate for 25 seconds. If the fuel is aerated, then check/repair fuel line and recheck.
With the fuel hose connected the fuel pressure should be 10psi. If the fuel delivery tests fail, replace the diesel fuel filter and recheck.
If it still fails then verify there are no restrictions in the fuel tank
Then replace the lift (transfer) pump. IT SHOULD BE NOTED that if this code surfaced after a routine fuel filter replacement or if you have any of the above symptoms after routine fuel filter replacement, then suspect the fuel transfer pump. This occurs because even a weak transfer pump can still provide enough fuel for the engine to run. But when the fuel system\'s prime is lost due to fuel filter replacement, it may not restart again without fixing the fuel delivery problem.
If you found your injection pump to be bad, the lift pump should be checked for operation to protect the new injection pump. This is because weak or low output from lift pump are common cause of injection pump failure. There are some aftermarket kits that can be purchased to warn the operator when the fuel pressure/volume drops to level that could damage the injection pump.

Yes it is a throttle body injection,looks very similar to an older style carburetor,warning! Do not turn ignition key on during removal of injectors,remove negative battery cable before removal,lightly coat rubber orings with petroleum jelly before installation.
Your 1989 cavalier is a 2 liter fuel injected engine so yes you do have a computer to run the engine so check your fuses and start with the simple and replace the fuel filter, air filter and clean the throttle body with throttle body cleaner. Don't use carburetor cleaner, the carburetor cleaner is to corrosive for the gaskets used in the throttle body. Also make sure all the vacuum lines are connected and not damaged, a bad vacuum line to the MAP sensor will cause what your having.
Good luck and keep us posted. Be glad to help you get your car running 100% again without the cost of a garage trying to be like the tax man.
Thank you for using Fixya
Yes sir , you have a failing valve, soon it will snap in two....please have your head checked. You can do this yourself by placing a long-handed screwdriver , business end down to each cylinder while pressing your ear to the handle(while engine is running)...you will notice a definite difference when you hit which cylinder has the bad valve. Also makes sure the egr valve is clean and your exhaust recycle valve is not stuck.( located in the crossover pipe)
The cheapest way to go is to change the fuel filters first and the air filter. Then I would change the crankshaft sensor.
You may have to bit the bullet , and have the fuel pump changed before the fuel injection pump. The fuel pump in the tank can be loosing pressure to the fuel injectoin pump.
I think the lesser cost is the fuel tank pump vs. the fuel injection pump.
The system runs of fuel and air. No spark like on a gas engine.
So the problem can only be lack of fuel or lack of air getting into the vehicle air induction. A restriction in fuel or air will make the engine run poorly.
