Need a fix for no injector pulse, cam signal, and no start


Have you checked to make sure the security system isn't preventing it from starting?

If not, the cam and crank sensor needs to correlate in order to have injector pulse and spark, so I would start by probing the cam sensor to check for AC current while cranking if there is current ohm the wires to the ecm, if the ohm reading is less than 1 ohm it sounds like a computer problem

This engine will not fire. I am getting fuel to the injectors. It runs on quick start and that is it. Do I have a problem with fuel pump timing or possibly an electrical problem?


probably a problem with the injectors or injector pulse run the fault code
check pump pressure if petrol or have an accredited diesel shop do it if common rail diesel
engine type not specified

How do I time the injector pump on a mitsubishi 4D33 . I can time the main gear no worries but how do I time the fine timing marks between the main pump and front pump housing / timing gear housing .


There is a timing light made for diesel engines works on the injector pulse and TDC mark . best bet take it to diesel service workshop, or buy one, not cheap.

98 eclipse 2.0 has spark but no injector pulse on #2 or #4


Injectors are pulsed by ECU using ground. You should check if there is any current coming out from fuse box.Most fuse boxes with injector fuses will share two injectors off one pin. So you may have two wires coming out from fuse box, and it is very common to be paired 1-3 & 2-4.

I have a 2006 Dodge ram diesal It acts like it ran out of gas thing is it just died It wasn't the gas I think it might be the brain so how could I don't troubleshooter It


Firstly dont talk and drive as you lose concentration and spill your drink,saciledge .Right 2006 diesel so its common rail ,now first thing to do is get the multimeter out and check you have a pulse to a injector when cranking the engine ,then work from their so if you have a pulse to a injector then its fuel ,now in the tank is a low pressure lift pump which supplies fuel when starting but lots of vehicles dont run this pump all the time ,now iam not familar with this american vehicle as to layout but at the end of the day its a diesel which i do most of my work on here in spain ,anything with more than 3 cylinders has to be a diesel here owing the price of fuel ,right check for a pulse first then slacken a diesel fuel pipe to one of the injectors and see if you have fuel pressure ,then post your findings and we will work out where to hit it and with size hammer that will fix it

Nissan patrol 2.8l no diesel to the injektors


to test the engine correctly you will need to buy or rent a NOID test light to hook into the injector rail leads to insure the computer is sending a pulse to the injectors if there is no! pulse or signal while cranking the the ECM has gone out . if there is a pulse then check the filters for water contaminents and air locking the secondary pump needs to be checked for pressure and internal failure as well also check the fuel check valve in the main injector pump for sticking shut as well those are the most common failures to that engine also on the main pump check the voltage at the injection pump to insure there is 12 volts with the key on

No electric pulse to injectors on 1994 ford f350 diesel turbo 7.3


Im confused how do you have a direct inject diesel in a truck made 3 years before ford had such a thing 94(suposed to ) has a indirect inject diesel there is no electric wires running to the injectors there's only a pipe with very high pressure fuel running thru it
are you sure your not confusing the glow plug wires ?
they only get power to them for like 30 seconds when first starting it

whats the real problem?
