Ok, I'm brand new here (like 5 minutes brand new) so bear with me. I have a 98 s70 t5 with a 2.3 turbo, 5 speed manual. I recently did a tune up (plugs, wires, cap and rotor) and know I have everything right, but it wouldn't start! This was 2 weeks ago, and I've been tracking and replacing since trying to get it running again. Aside from the above listed parts, I have a brand new msd coil, battery, coolant temp sensor, and cam sensor. I checked the crank sensor and that was fine. I'm getting spark, I'm getting fuel, but still no start! The car cranks, and the engine kinda jumps like it wants to start, but still nothing. I've kinda narrowed it down to either the timing belt jumped (must've been a lot to cause no start instead of just running rough) or a bad ECM? Any suggestions or tips would help. I have the car about a month and a half now and was running great beforehand. I'm new to volvos (first import actually) and was thoroughly loving it! I'm surprised it was even running before once I saw how bad the plugs really were. But once again, any help would be greatly appreciated! Oh! Also, the CEL was on before this, never reset, and still on now, but when I hook up my scanner it says there are no codes stored. Before there was a 445(I believe) for evap emissions leak. Like I said, it's weird that it was throwing a code before, and not now. That's why I'm kinda leaning towards a bad ecm

 

Also, I've tried the teaspoon of oil in cylinders, and put brand new spark plugs (Bosch platinum before oil, ngk iridium afterwards)

 

Hi Wes, welcome to the forum.

First check the wire order, then all of the turbo tubes to make sure none are loose, then the fuel injector relay.

 

 

Thank you for the reply! I know the wires are right (checked several times),
I know the relay is good also. I'm having a buddy tow it this morning to a shop and have them (hopefully) fix it haha. I'm pretty decent mechanically and can't figure it out, niether can any coworkers or anyone I've told about iy

 

Most diagrams have the wire order wrong for some reason. Hope they get it figured out.

There is a common issue with these cars not starting after a motor change when a motor has sat un attached to a car for a while. The thing is, I'm not sure if those cars crank or not. It is a grounding issue and what most people have to do is take the motor out, clean the mounting point on the flywheel real good and the mating surface on either the motor shaft or torque converter (not sure which, they don't get that detailed). Then put everything back together and it fires right up. Essentially it is a problem with the motor getting a good ground with the car. I have seen a car with a monster size cable attached to the block and body of the car, pretty ugly but hey, it runs.

 

Well I took it to a shop this morning, and after two hours of fighting with it they figured it out! Turns out that there are two firing orders for these cars! Chiltons, my old distributor cap, various websites, and your picture identify the same one, but apparently there's two? Once I figure out how to post pictures here I will trace the wires, mark them attached to the cap, and post it so other people don't have to pay 200$ just for wires in the wrong spot like I did. Luckily she's fixed, and running amazing with 283000 miles . Thank you for your help!
