Hello Guys,

sadly my Truck (318 W150) wont start, without me adding fuel externaly in the intake.
I found out, my fuelpump was bad and i replaced it, new Filter and some lines. Got (fresh) fuel up to the injectors right now.
The injectors seems to work, when i add 12v to them (click). Unfortunatly, i just measure just 1V at the injectors while cranking.
Still looking for the problem there, hope i can spend more time with this between christmas.
My O2 Sensor is just dangeling around (preowner installed Headers) - is this probably a weak point in therms of electronics, because there is a ground missing?
Im planing to weld a bung and integrate the sensor asap.

Within the last weeks i demounted the TBI Body. Sadly i found out that one vacuuminlet is broke off.
When i check for an replacement (for the whole throttle body) my partnumber puts out an TBI body for an 3.9l V6 Dakota.
Are they the same/interchangeable, or is mine probably a wrong replacement here?

Does it stay running when you add fuel?

Yea, with the O2 sensor not working, it will just stay in the warm up mode, and use extra fuel at a minimum.

I do believe the 318 and 3.9 are different, but cannot say.

Hey George,

no, it stalls when i stop adding fuel externaly.
The injection seems not to in inject i guess, probably due the low voltage isnt enough to get the injectors starting.
Not sure though, fitment is flawless in my opinon.

Thanks for your feedback on the O2 sensor, i really appreciate it.

Have you loosened the fuel inlet into the TB, and verify fuel is getting there?

 

[Tom95]

Yes, Fuel comes into the injectors. Injectors are "flooded" if you look to the screen, but wont inject.
It must be an eletrical issue, due the injectors dont get the signal to fire.
Maybe a bad ground, broken wire or no signal from distributor due the turning cycle of the engine for the PCM/ECM comes from the distributor i believe.

 

[ToxicDoc]

No signal to fire is commonly the Hall effect sensor not working correctly inside the distributor. It acts as a cam/crank position sensor and can be bad even without an error code being present

 

[Tom95]

Hey Doc, this does make sense!
Did you know what it outputs when cranking?
Is asume 12v, per revolution of the distributor?

Now it makes sense, that the Distributor looks brandnew in total...

Sadly i think i need to replace the TBI body due the broken inlet/vacuum.

 

[ToxicDoc]

I do not know the voltage sorry.

 

[Mopar572]

It wouldn’t run with gas down the TB if the Hall effect was bad, when the Hall effect goes you have no spark

 

[Tom95]

Hey Mopar,

seems to make sense, cause i got spark.
Yesterday i talked to my admission inspecor, he said if there is absolute no way to get it right - my only escape route is to use an aftermarket EFI.
Concidering the tax and delivery it is a quite simple task, if there are several more problems with the TBI i am not willing to rebuild this system cause there are almost no spares available here in Germany.
The Sniper EFI goes for around 2k€ here, new intake is in stock in europe.
In adittion i need to look after my trans, but i dont think i have an overdrive.
AC/Voltage regulator is also on list to deal with in this case.

Before you write it off, check for codes.

Thank you, thats the post i was reading yesterday and forgot to save myself.

Does anyone redrilled and thread a new fitting into the throttle body?
(vacuum port, picture below)
The port is for the diverter valve niple, i think i can probably negate this and block it with .. i dont know yet what.

I am also not sure if my TBI is the right one, could somebody check theirs on the 318 please?

No overdrive was available in a '89 4X4, and the voltage regulator is part of the ECM. If the Sniper is legal to use I'd highly recommend it over the stock TBI system for several reasons, parts availability being one and the increased performance being another.

 

[Tom95]

Yes. My inspector is Kind enough to admit that the Holley TBI and the sniper equals eachother enough in function, that he let me pass inspection with it. He also says, an aftermarket intake is basicly an known customisation. He further lets me mount the Hooker exhaust system, including the headers, if i install two universal catalytic converters in them. System must be within german regulations of course (90db).
I really like his kindness cause it gives me much more freedom and the sniper as an backup, if i did not sort out the TBI.
oh, smog delete is also ok in use with universal catalytic converters.
But 02 sensor have to stay, but thats no big deal cause TBI and Sniper need it anyways.

But first i will stuck to the TBI, even if my heart would love to install the sniper with an better intake.

I am realistic, if major Parts like the TB or ECM fails, it is by far more painful to Order used or refurbished stuff from over the states, than pick up an sniper System that already is available over here in Germany and start of from the ground up.

But we will see.

How are the longterm tests of the Holley Sniper EFI?

OD gets into the W‘s at later Models?
great to hear that! 👍🏻 Thanks

The A518 overdrive was first used in '90, mostly behind 360s. And speaking of 360s the cam from a '89-92 makes a noticeable improvement in a 318, the vin "Z" version is more of of torque/towing cam in a 360 but in a 318 it's more of a mid range street cam.


I've installed several Snipers, all but one have done extremely well for years so far, the one that was defective was caused by welding on the exhaust system without unhooking the battery we believe. The Sniper on my truck hasn't been on that long but it's doing very well other than a faulty IAC servo, easily replaced under warranty.

 

[ToxicDoc]

If he lets you do the Sniper, do that. It is vastly superior. The TBI is a fairly primitive system.

that plate comes right off , just need a new one / besides l,d fix it

the 1989 318 TBI is # 4306 593

Hey Guys,

thank you really much for your sweet assitance!
My plan is to get deeper into it, around next week.
With all your support im hoping to get it fixed or at least, figure out whats particularly wrong with my injection.
If i get it running, i promise a nice Video of it!

 

[Tom95]

Guys, finally! It runs!
You wont believe what caused it.
The injectors get the + in my case somewhere from the mainharness, probably from the headlight (looks like done afterwords, pretty bad work)
I also noticed that my headlight arent working, so i kept looking that direction.
Under the steering column i found a melted coupler. The - comes from the ECU.
so i created a temporary wiring on the fly, directly from the battery. And you wont believe it, it started asap.
I actually cant believe it.
Im pretty happy, thank all of you guys for your help.

If you are interested i can upload a video on YT, but an 318 running is probably not the most entertaining thing.

I finished the day of with some beers,rum and beefed ribeye.
