All of this info is in the original service manual. If it stops before it dies it may be a faulty resistor pack for the injectors, bad wiring or bad ecm. If it is an injector problem their wiring must be inspected, test them with a lite to see if it stops blinking before or after it dies. Just to be sure, make sure your fusible links are good and not fried. I believe this relay is normally closed and it would pass relay power through its contacts. Cleaned up, inspected and ready to install on a high quality Datsun Z car Price Note: Tube comes with upper collar attached, as in photo, for advertised price.
Make sure your coolant temperature sensor connector is in good shape I've seen the harness connector short on one 280zx. This example includes my hand-printed notes and colored highlighting. The fuel pump is new and i added a new fuel filter. If it drops off before engine dies it is a supply problem pump filter and lines if after it will be on the injector side. Thanks for your help, Bill Can I wire the fuel pump on my 76 280z through a seperate switch from the battery to the pump for test purposes to get the engine running? If the connection is loose, and you make connection by twisting back and forth, you should hear the ignition relay click on and off, and then get your +12V on pin 10.
I dont see 12V on pin 10 of the harness. I want to be sure about it and i want to test the unit itself. In theory, when the Bosch mechanical airflow meter detects air flow through the engine, a mechanical switch should close to keep the fuel pump running. Since 1919, Standard Motor Products has engineered a full line of engine management products, including ignition parts, sensors and on-board computers. The major influences are changes in temperature, humidity and electrical load through the ground connection.
My bet is that you have a loose connection in there. Therefore the car dies after a few secs. Edited July 30, 2012 by z240 Do you want that one just to keep it all stock looking? Compression and base ignition timing were at specification even as the base idle speed needed some slight adjustment. Bill Well I was wrong, new ignition switch is not it. I think the Fuel pump circuit is on a 15A fuse, so a 20A relay should be fine. I dont want to crank the car since its night but tomorrrow morning i will test some more.
Very common problem in these cars. You can pry the tabs back on the case also, and take it apart if you want to check the guts out for rust and corrosion. Removal of the cranshaft is staight forward. I've got a 76 Z myself. One red wire attached to the battery positive terminal appeared stock. I would have spent days more except I found it by removing the relay from the metal can around the fuel pump relay and watching the coils energize. I also noticed that two large red wires were attached to the battery positive terminal and that the battery negative cable had an open connector bay.
See photo 3 My next step was to see if the fuel injectors were pulsing. How do you clutch bleed? Since ground resistance varies according to temperature, humidity and electrical load, a bad ground circuit can cause multiple trouble codes to be stored at random in the diagnostic memories of the engine, body-control and other modules. Bill Well I was wrong, new ignition switch is not it. The main relay is suspended at the top left center of the photo. With the key on the on position I held open the afm flapper and the fuel pump ran. If so, this red wire should show battery voltage when removed from the B+ terminal connector.
Please contact us first for details before purchasing this unit online. One person in the cab to work the clutch pedal. Grounding the wire with another jumper wire produced no change. I'll dig through my box-o-relays for one, but don't hold your breath. Requires the removal of the distributor, oil pump and pump drive shaft from cover, first. It fixed a problem I had that when I turned on the head lights with the engine running the engine died. The S30 is a 12V system.
As suggested, open up the one you got and trouble shoot it. Since 1919, Standard Motor Products has engineered a full line of engine management products, including ignition parts, sensors and on-board computers. Pulsing of the injectors is all you need. Bad ground do many bad things that are hard to identify. My guess is some rust or crud is stuck in your fuel system, is lowering your fuel pressure and causing your car to stall. The engine immediately started and kept running as long as I supplied propane. Not an auto repair expert? A failed tps will cause drivability issues, normally it won't cause engine to die.
Has the car been sitting for any long amount of time? This shows the componets in the mix here are Battery, Fusible Link, Ignition Switch, Fuel Pump relay, harness and the Control Unit. During warm-up, a rough engine indicated that several fuel injectors were slightly fouled. Can't get the nipple open? I tested all the fusible links inside the passengers compartment and all have continuity. These fuses should be within 0. I ended up bending the switch mechanism so that it would stay closed at lower air flow. Diagnosing Fuel Delivery To test the ignition system, I introduced propane into the air intake while cranking the engine.
