Question about 2007 Chevrolet TrailBlazer SS

1 Answer

My neighbor has a 2007 Trailblazer SS. It will crank but no start. Checked fuel pressure good at 58 no bleed down.Replaced ignition box, same problem. Hooked it up to a Snap-on scanner tested check engine light, it will turn on and off we can also activate relays with it so we think the PCM is good. With the scanner hooked up we cycle the ignition and we get an RPM reading upon cranking but no start so we think the crank sensor is good because of RPM reading.Have not checked the cam sensor yet, but also noticed that we drained the battery so we slow charged it over night and now after two maybe three cycles of the ignition the battery is low on power. Can anyone offer anymore advice on this matter. Also after the initial first time truck shut down it restarted after about 5 min. this happened 2 times now just Crank No Start with NO Spark. No Spark seems to be the problem. BUT WHY!

I'm having trouble starting my 2007 1.9 cdti in cold weather. Replaced the relay, glow plugs are good. Could it be the temperature sensor?


unlikely
it is more likely that the cranking speed is too slow for the compression pressure to get hot enough to ignite the fuel
2 possible fixes
the battery has to be in top condition for cold weather starting
and
the injectors may be squirting and not atomizing so have them professionally checked at a specialist diesel shop

I have a 1987 chevy pick up truck.There is no fuel coming out of the injectors. Cant figure out why


First, make absolutely sure the fuel pump is running when the key is on and is pushing fuel to the TBI. Take the feed line off the TBI if you have to. Watch it, fuel will spray everywhere if you aren't careful. Most fuel pump "no run" problems are caused by a bad ground. Use a VOM to check for power and ground.

Make sure the injectors receive power when the engine is cranking to start. Might be something as simple as a blown fuse. Can check with a noid light or 12v test light. Remote possibility of the injectors losing power when via the ignition switch and/or wiring when you crank the engine.

Fuel pressure regulator may be defective. TBI must be disassembled to replace it. There is a nice aftermarket adjustable regulator available.

Internal to the TBI itself (SOME, BUT NOT ALL HAD THIS) is a small neoprene pressure bleed. It has a VERY small hole in it, used to slowly bleed off the fuel pump pressure when the engine is shut down. If the diaphragm ruptured the fuel will return to the tank, never building enough pressure to spray out the injectors.

These units are relatively easy to rebuild. Youtube has several good vids walking you thru the process if you have any doubts.

sure, sounds like he knows his way around the engine. Does he have a multi-meter? What I would do is check the injectors and ignition coils to see if they are getting AC voltage while you are cranking the engine. This will tell us if the problem is fire or fuel. We can then go from there.

Replaced injector pump and fuel filter still starts hard


system may be bleeding down thru leaky injectors. Try turning ignition on and off several times before cranking. This will help the pump pressurize the system. If this works, you know your system is bleeding down. Let me know if you have questions.

Starting car is problem. it will start after maybe two trys. i have tried engine cleaner, but still it is slow starting,. battery is good, thats been checked.


When you have an engine that is hard to start or the engine takes longer than normal to start, with a fuel injected engine it will normally be caused by a fuel problem. Another problem would be slow cranking of the engine because of a low battery, I would check all of the fuel related problems if the engine seems to crank normally. There are a few things to check. First pull the fuel filter off and wipe it off so you don't get gas in your mouth and try to blow through one of the fuel connections on the filter. If you can't blow through it the filter is pluged and needs to be replaced. A plugged fuel filter can cause hard starting and can also damage your fuel pump. The next thing to do when everything is put back on the car is to check the fuel system for bleed down. You need to locate the fuel pressure test connection on the engine. Connect a fuel pressure gauge to the connection and start the engine, then turn the ignition off. With the engine off the pressure should read and stay between 30psi and 40psi, to be sure of the pressure you will have get the spec's on the engine you have. The main thing you will be looking for is to make sure the pressure doesn't start bleeding down in to direction of zero after a few minutes or maybe even immediately. If you see the pressure start to bleed down you have a problem. There are two problems that normally cause the pressure to bleed down. One is a bad check valve in the fuel pump, the other is a bad fuel pressure regulator. The main thing that happens with a fuel pressure regulator is the diaphram inside starts leaking. When that happens sometimes it will leak fuel into the intake manifold through the vaccuum hose connection to the intake manifold. To check for a fuel leak through the vacuum hose connection, locate the vacuum hose on the fuel pressure regulator and pull the hose from either the manifold connection or from the connection at the fuel reguator. If you see any gas at all the fuel regulator is leaking and must be replaced. If it is a slow leak from the regulator you might have to start the engine with the vacuum hose disconnected and look for a leak from the hose. If you don't find anything wrong with the regulator the next problem area would be fuel pressure bleeding back into the gas tank because of a bad check valve in the fuel pump. If this is the problem the fuel pump would have to be replaced. My first guess as to what is causing your problem would be the fuel pressure regualtor although I would definately want to make sure the fuel filter is not plugged. (Please Note) The fuel pressure regulator is located in the intake manifold area of the engine. The fuel pump is located in the gas tank. The fuel filter is located usually somewhere under the car.

first, check all the fuses
did you check to see if there's spark at spark plugs?
did you check the fuel pressure? you need to do that to isolate fuel and ignition system.
if there is no fuel then check for fuel pump operation
if there is no spark then check the ignition system (coil, module and wirings)
if you don't have either one then the problem is in the computer system such as crank sensor, and computer itself

Completed tune up, drove for 2 blocks, engine shut down


Just having fuel is not enough on this engine, here are the spec's. Even 1 psi out of spec can cause a no start.

Fuel Pressure
Pressure 1 (PSI) Pressure 2 (PSI) Pressure 3 (PSI) Range Note Range Note Range Note 60.0 - 66.0 Y131 50.0 - 63.0 Y132 66.0 Y133 Y131: System pressure with ignition on (PSI).
Y132: System pressure while idling (PSI).

there is a fuel pressure regulator on the back of your injectors, change it, its a 13 dollar part, after you do that, buy a fuel pressure guage, hook up the pressure guage, turn the key to on possition, prime the like a couple times like you would do with a new pump, check the pressure it should be any where from 58 LBS to 62 lbs of pressure in the like, if its any lower the 58, you need to change your pump, with out 58 lbs of pressure the injectors dont get the correct pressure in each purge, hence the crank with no start.. you seem to know enought about pressure n stuff like that so u should get it
