    Volvo 940 Rex Regina Fuel Pump Alternatives

    By TomServo

    Hello! I had to replace my 1994 Volvo 940’s (normally aspirated with Rex Regina) fuel pump over the summer. It was found with very low pressure, about 15psi. The relay and fuse are good and the filter is new. It failed again recently. I checked the pressure and saw it down to 7psi before it failed. Does anyone know of another pump that could work in the single in tank pump Rex Regina set up? I’ve heard of people using the Walbro GSS342. Has anyone had luck with this or know what... Read more

    Airconditioning on a turbo LS car?

    By turbojose

    I'm a little torn between pull the 16v out and put in the turbo LS, all of the parts are already purchased... but I'm looking at other threads, and I don't see anyone running air conditioning. I'm not sure that is something I want to give up. Are there any air conditioned turbo LS 240's our there? I would love to see your setup and talk about how you packaged it all.

    +T or engine swap… thinking out loud

    By VWJake

    With diesel prices at $7/gal here it’s no longer reasonable to drive my 14mpg truck. So, out comes my ‘76 265 to reclaim DD status. I guess it’s really only a 265 in title. Brakes, Suspension, AW70, and rear axle (open 3.73) came from an ‘85 245. Engine is a ‘93 B230F that I shaved .040” off the head and added an ipd Vx3 cam and a nuke adj timing gear to. LH2.4 ECU and EZK came from same ‘93. Wiring harness is from a 740 LH2.4 turbo car (whittled down to fit my car). The car has functional... Read more

    1989 240 Part ID please?

    By kydave19

    While removing the useless AC line going through the firewall today, after removing the compressor it was no longer hooked up to yesterday, I noticed a similar looking hose going through the firewall. It comes from this "Filter-Dryer..." canister next to the radiator (passenger side). Is this part of the AC system? If so, can I toss the hose and canister? Or is it actually something my old car is using? Thanks as always for helping my learning curve on my "new-to-me" 240!

    Bright Silver paint code the same for cars and OEM wheels?

    By FlyingTog

    I'm not on social media or any other Volvo sites. Trying to find out if the Bright Silver paint code (711) is the same for wheels and cars. So far I haven't found anything that says they're not but no confirmation that they are either. Trying to get my Pegs refinished and I want to make sure I get the right color put on them. P.S. The internet sucks now.

    Failing CA Smog

    By Vibe Father

    So I just got a new factory turbo, downpipe, oil cooling lines, and coolant lines replaced on my 1990 740 Turbo wagon, and I finally went to get it smogged and it failed for too much NO, CO, and HC. It passed the visual and functional. Here are the values, if helpful. I’m also including a picture. HC Max allowed: 80 @ at 15mph, 62 @ 25mph. HC Measured: 101 @ 15mph, 94 @ 25mph. CO Max allowed: 0.52 @ 15mph, 0.42 @ 25mph. CO Measured: 0.53 @ 15mph, 0.44 @ 25mph. NO Max allowed: 549 @... Read more

    Volvo 940 rear door stuck closed after replacing exterior handle. Won't open from inside or outside

    By gtejegar

    Hi everyone, I'm having an issue with the rear door of my Volvo 940 after replacing the exterior door handle, and I'd appreciate some advice before I start taking things apart again. Yesterday, I replaced the exterior handle, and everything seemed to work perfectly. I tested opening and closing the door several times from both inside and outside, with no issues. However, as soon as I locked the car and tried to unlock it again, the door became completely stuck. Here's what I've noticed... Read more

    940 Turbo Barn Find ~6 years sitting

    By Moyni

    I recent bought a 94 940 turbo, one owner car that has been sitting in a garage for the past 6 years after its owner passed away in 2020. Its all in nice shape, good service records, good paint, etc. I am doing the obvious stage 0 work to get it to run, just wanted some opinions on what parts to get. I just replaced all the fuel pumps and filters since the gas was super varnished. The in tank sender was reading okay before I pulled it, now its a borderline open circuit (like... Read more

    240+t build and 2/7/940 Ecu and Ezk questions

    By Sk00bie

    Hi there guys I have a 1993 volvo 244 N/A +t its an LH 2.4 car and it’s got a td04 13c, 940 intercooler and rad, orange top injectors with a 0 280 000 954 ecu and a 0 227 400 207ezk. The computers were from an unknown turbo egr car so they throw codes but I don’t believe that would cause any running issues, correct me if i’m wrong. The car has had all the afr lean/rich codes since being turboed but for the most part has run well once the computers adapt. I have a wideband gauge but I believe... Read more

    Sensor Help!

    By HBenning

    This has been talked about quite a bit so I'm sorry in advance for starting another thread on this but I want to make sure I'm seeing this correctly. I've been chasing a slightly uneven idle and rough winter cold starts in my 93' 245 for a long time now and have had issues with my Coolant Temp Sensor before. Car has always started but can have a bit of a lope in cold temps as it warms up. I also have a small hot start issue where the car will rev to about 3000-3500 rpm then drop back down... Read more

    940 cruise control not working

    By haydnharvespa

    good morning guys, i have been driving my 940 longer distances north back into town from where I live, and the lack of functional cruise control is a major gripe for me. All my vacuum lines and bellows are in good shape but no matter what i do, I get no response from the CC system. I was trying to look at links in older forum posts to help me diagnose, but most of the links i click are dead. If anyone has any links to useful diagnostic information, I would appreciate seeing them. I don't... Read more

    Bypass/Remove AC and keep PS

    By dcumberland

    My 82 245 has been making an awful rattle at low RPMs. I've isolated the issue to the AC compressor. The ac hasn't functioned as long as I've owned the car and it's not even plugged in. When I take the belt off, the sound is gone. I could get a different AC unit from a junker, but I'd rather just not bother. I'm curious if anyone has moded the PS so that you could get a belt onto it without the AC?

    90 745 Regina code 3-2-1, REX code 1-4-3, low power & shaking at idle/during acceleration.

    By DET17

    My wagon has currently thrown these CEL codes. Power is down, and idle quality is poor, lots of shaking. The day before when it initially starting running poorly, the Fuel code thrown was a 2-3-1, while the ignition code was the same as today. AFAIK, the car has an older O2 sensor.... these apparently are getting pretty scarce based on items for sale. Today I disconnected the power flat blade connector and cleaned it well, reassembled and the code didn't reoccur. GOOG AI claims this... Read more
